# Accordion An accordion is a vertically stacked set of interactive headings containing a title, content snippet, or thumbnail representing a section of content. ## Resources [Latest version: v1.7.0](https://www.npmjs.com/package/@zag-js/accordion) [Logic Visualizer](https://zag-visualizer.vercel.app/accordion) [Source Code](https://github.com/chakra-ui/zag/tree/main/packages/machines/accordion) **Features** - Full keyboard navigation. - Can expand one or multiple items. - Collapse each accordion item. ## Installation To use the accordion machine in your project, run the following command in your command line: ```bash npm install @zag-js/accordion @zag-js/vue # or yarn add @zag-js/accordion @zag-js/vue ``` This command will install the framework agnostic accordion logic and the reactive utilities for your framework of choice. ## Anatomy To set up the accordion correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Usage First, import the accordion package into your project ```jsx import * as accordion from "@zag-js/accordion" ``` The accordion package exports two key functions: - `machine` — The state machine logic for the accordion widget. - `connect` — The function that translates the machine's state to JSX attributes and event handlers. > You'll also need to provide a unique `id` to the `useMachine` hook. This is > used to ensure that every part has a unique identifier. Next, import the required hooks and functions for your framework and use the accordion machine in your project 🔥 ```html ``` You may have noticed we wrapped each accordion trigger within an `h3`. This is recommended by the [WAI-ARIA](https://www.w3.org/TR/wai-aria-practices-1.1/#wai-aria-roles-states-and-properties) design pattern to ensure the accordion has the appropriate hierarchy on the page. ## Opening multiple accordions at once To allow multiple items to be expanded at once, set `multiple` to `true`. This mode implicitly sets `collapsible` to `true` and ensures that each accordion can be expanded. ```jsx {2} const service = useMachine(accordion.machine, { multiple: true, }) ``` ## Opening specific accordions To set the value of the accordion(s) that should be opened initially, pass the `value` property to the machine function. ```jsx {3,4,9} // for multiple accordions const service = useMachine(accordion.machine, { multiple: true, defaultValue: ["home"], }) // for single accordions const service = useMachine(accordion.machine, { defaultValue: ["home"], }) ``` ## Toggle each accordion item To collapse an already expanded accordion item by clicking on it, set the context's `collapsible` property to `true`. > Note: If `multiple` is `true`, we internally set `collapsible` to be `true`. ```jsx {2} const service = useMachine(accordion.machine, { collapsible: true, }) ``` ## Listening for changes When the accordion value changes, the `onValueChange` callback is invoked. ```jsx {2-5} const service = useMachine(accordion.machine, { onValueChange(details) { // details => { value: string[] } console.log("selected accordion:", details.value) }, }) ``` ## Disabling an accordion item To disable a specific accordion item, pass the `disabled: true` property to the `getItemProps`, `getItemTriggerProps` and `getItemContentProps`. When an accordion item is disabled, it is skipped from keyboard navigation and can't be interacted with. ```jsx //...

Content
//... ``` You can also disable the entire accordion items by passing `disabled` to the machine's context. ```jsx {2} const service = useMachine(accordion.machine, { disabled: true, }) ``` ## Styling guide Earlier, we mentioned that each accordion part has a `data-part` attribute added to them to select and style them in the DOM. ### Open and closed state When an accordion item is expanded or collapsed, a `data-state` attribute is set on the item, trigger and content elements. This attribute is removed when it is closed. ```css [data-part="item"][data-state="open|closed"] { /* styles for the item is open or closed state */ } [data-part="item-trigger"][data-state="open|closed"] { /* styles for the item is open or closed state */ } [data-part="item-content"][data-state="open|closed"] { /* styles for the item is open or closed state */ } ``` ### Focused state When an accordion item's trigger is focused, a `data-focus` attribute is set on the item and content. ```css [data-part="item"][data-focus] { /* styles for the item's focus state */ } [data-part="item-trigger"]:focus { /* styles for the trigger's focus state */ } [data-part="item-content"][data-focus] { /* styles for the content's focus state */ } ``` ## Creating Component Create your accordion component by abstracting the machine into your own component. ### Usage ### Implementation Use the the `splitProps` utility to separate the machine's props from the component's props. ## Methods and Properties The accordion's `api` exposes the following methods and properties: ### Machine Context The accordion machine exposes the following context properties: **`ids`** Type: `Partial<{ root: string; item(value: string): string; itemContent(value: string): string; itemTrigger(value: string): string; }>` Description: The ids of the elements in the accordion. Useful for composition. **`multiple`** Type: `boolean` Description: Whether multiple accordion items can be expanded at the same time. **`collapsible`** Type: `boolean` Description: Whether an accordion item can be closed after it has been expanded. **`value`** Type: `string[]` Description: The controlled value of the expanded accordion items. **`defaultValue`** Type: `string[]` Description: The initial value of the expanded accordion items. Use when you don't need to control the value of the accordion. **`disabled`** Type: `boolean` Description: Whether the accordion items are disabled **`onValueChange`** Type: `(details: ValueChangeDetails) => void` Description: The callback fired when the state of expanded/collapsed accordion items changes. **`onFocusChange`** Type: `(details: FocusChangeDetails) => void` Description: The callback fired when the focused accordion item changes. **`orientation`** Type: `"horizontal" | "vertical"` Description: The orientation of the accordion items. **`dir`** Type: `"ltr" | "rtl"` Description: The document's text/writing direction. **`id`** Type: `string` Description: The unique identifier of the machine. **`getRootNode`** Type: `() => ShadowRoot | Node | Document` Description: A root node to correctly resolve document in custom environments.

It provides an intuitive way to control rotations or orientations, offering accessibility features. ## Resources [Latest version: v1.7.0](https://www.npmjs.com/package/@zag-js/angle-slider) [Logic Visualizer](https://zag-visualizer.vercel.app/angle-slider) [Source Code](https://github.com/chakra-ui/zag/tree/main/packages/machines/angle-slider) **Features** - Fully managed keyboard navigation. - Supports touch or click on track to update value. - Supports Right-to-Left directionality. ## Installation To use the angle slider machine in your project, run the following command in your command line: ```bash npm install @zag-js/angle-slider @zag-js/vue # or yarn add @zag-js/angle-slider @zag-js/vue ``` This command will install the framework agnostic angle slider logic and the reactive utilities for your framework of choice. ## Anatomy To set up the angle slider correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Usage First, import the angle-slider package into your project ```jsx import * as angleSlider from "@zag-js/angle-slider" ``` The angle slider package exports two key functions: - `machine` — The state machine logic for the angle slider widget as described in the WAI-ARIA spec. - `connect` — The function that translates the machine's state to JSX attributes and event handlers. > You'll need to provide a unique `id` to the `useMachine` hook. This is used to > ensure that every part has a unique identifier. Next, import the required hooks and functions for your framework and use the angle slider machine in your project 🔥 ```html ``` ## Setting the initial value ```jsx {2} const service = useMachine(angleSlider.machine, { defaultValue: 45, }) ``` ## Setting the value's granularity By default, the granularity, is `1`, meaning that the value is always an integer. You can change the step attribute to control the granularity. For example, If you need a value between `5` and `10`, accurate to two decimal places, you should set the value of step to `0.01`: ```jsx {2} const service = useMachine(angleSlider.machine, { step: 0.01, }) ``` ## Listening for changes When the angle slider value changes, the `onValueChange` and `onValueChangeEnd` callbacks are invoked. You can use this to setup custom behaviors in your app. ```jsx {2-7} const service = useMachine(angleSlider.machine, { onValueChange(details) { console.log("value is changing to:", details) }, onValueChangeEnd(details) { console.log("value has changed to:", details) }, }) ``` ## Usage within forms To use angle slider within forms, use the exposed `hiddenInputProps` from the `connect` function and ensure you pass `name` value to the machine's context. It will render a hidden input and ensure the value changes get propagated to the form correctly. ```jsx {2} const service = useMachine(angleSlider.machine, { name: "wind-direction", }) ``` ## Using angle slider marks To show marks or ticks along the angle slider track, use the exposed `api.getMarkerProps()` method to position the angle slider marks at desired angles. ```html {10-16} //...
//... ``` ## Styling guide Earlier, we mentioned that each angle slider part has a `data-part` attribute added to them to select and style them in the DOM. ### Disabled State When the angle slider is disabled, the `data-disabled` attribute is added to the root, label, control, thumb and marker. ```css [data-part="root"][data-disabled] { /* styles for root disabled state */ } [data-part="label"][data-disabled] { /* styles for label disabled state */ } [data-part="control"][data-disabled] { /* styles for control disabled state */ } [data-part="thumb"][data-disabled] { /* styles for thumb disabled state */ } [data-part="range"][data-disabled] { /* styles for thumb disabled state */ } ``` ### Invalid State When the slider is invalid, the `data-invalid` attribute is added to the root, track, range, label, and thumb parts. ```css [data-part="root"][data-invalid] { /* styles for root invalid state */ } [data-part="label"][data-invalid] { /* styles for label invalid state */ } [data-part="control"][data-invalid] { /* styles for control invalid state */ } [data-part="valueText"][data-invalid] { /* styles for output invalid state */ } [data-part="thumb"][data-invalid] { /* styles for thumb invalid state */ } [data-part="marker"][data-invalid] { /* styles for marker invalid state */ } ``` ### Styling the markers ```css [data-part="marker"][data-state="(at|under|over)-value"] { /* styles for when the value exceeds the marker's value */ } ``` ## Methods and Properties ### Machine Context The slider machine exposes the following context properties: **`ids`** Type: `Partial<{ root: string; thumb: string; hiddenInput: string; control: string; valueText: string; }>` Description: The ids of the elements in the machine. Useful for composition. **`step`** Type: `number` Description: The step value for the slider. **`value`** Type: `number` Description: The value of the slider. **`defaultValue`** Type: `number` Description: The initial value of the slider.

This component builds on top of the native `` experience and provides a more customizable and consistent user experience. ## Resources [Latest version: v1.7.0](https://www.npmjs.com/package/@zag-js/color-picker) [Logic Visualizer](https://zag-visualizer.vercel.app/color-picker) [Source Code](https://github.com/chakra-ui/zag/tree/main/packages/machines/color-picker) **Features** - Support for custom color area - Support for RGBA, HSLA, HEX, and HSBA formats - Support for channel inputs and sliders - Support for mouse, touch, and keyboard interactions - Support for form submission and reset events - Support for named css colors ## Installation To use the color picker machine in your project, run the following command in your command line: ```bash npm install @zag-js/color-picker @zag-js/vue # or yarn add @zag-js/color-picker @zag-js/vue ``` This command will install the framework agnostic color picker logic and the reactive utilities for your framework of choice. ## Anatomy To set up the color picker correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Usage First, import the color picker package into your project ```jsx import * as colorPicker from "@zag-js/color-picker" ``` The color picker package exports these functions: - `machine` — The state machine logic for the color picker widget. - `connect` — The function that translates the machine's state to JSX attributes and event handlers. - `parse` - The function that parses a color string to an Color object. Next, import the required hooks and functions for your framework and use the color picker machine in your project 🔥 ```html ``` ## Setting the initial value To set the initial value of the color picker, use the `value` context property. ```jsx const [current, send] = useMachine(colorPicker.machine, { defaultValue: colorPicker.parse("#ff0000"), }) ``` ## Listening for change events When the user selects a color using the color picker, the `onValueChange` and `onValueChangeEnd` events will be fired. - `onValueChange` — Fires in sync as the user selects a color - `onValueChangeEnd` — Fires when the user stops selecting a color (useful for debounced updates) ```jsx const [current, send] = useMachine(colorPicker.machine, { onValueChange: (details) => { // details => { value: Color, valueAsString: string } }, onValueChangeEnd: (details) => { // details => { value: Color, valueAsString: string } }, }) ``` > When using the `onValueChange` method in React.js, you might need to use the > `flushSync` method from `react-dom` to ensure the value is updated in sync ## Using a custom color format By default, the color picker's output format is `rgba`. You can change this format to either `hsla` or `hsba` by using the `format` context property. When this property is set, the `value` and `valueAsString` properties of the `onValueChange` event will be updated to reflect the new format. ```jsx const [current, send] = useMachine(colorPicker.machine, { format: "hsla", onValueChange: (details) => { // details => { value: HSLAColor, valueAsString: string } }, }) ``` ## Showing color presets Adding color presets in form of swatches can help users pick colors faster. To support this, use the `getSwatchTriggerProps(...)` and `getSwatchProps(...)` to get the props needed to show the swatches buttons. ```html ``` ## Disabling the color picker To disable user interactions with the color picker, set the `disabled` context property to `true`. ```jsx const [current, send] = useMachine(colorPicker.machine, { disabled: true, }) ``` ## Controlling the open and closed state To control the open and closed state of the color picker, use the `open` and `onOpenChange` context properties. ```jsx const [current, send] = useMachine(colorPicker.machine, { open: true, onOpenChange: (details) => { // details => { open: boolean } }, }) ``` You can also leverage the `api.setOpen(...)` method to control the open and closed state of the color picker. ## Controlling individual color channel In some cases, you may want to allow users to control the values of each color channel individually. You can do this using an input element or a slider element, or both. To support this, use the `getChannelInputProps(...)` to show the channel inputs. > Note: Make sure you only render the channel inputs that match the `format` of > the color picker. ```html ``` ## Showing a color preview To display the value of a color, use the `getSwatchProps(...)` and pass the color value. To show the current color value, use the `api.value` ```html ``` > You can pass `respectAlpha: false` to show the color value without the alpha > channel ## Adding an eyedropper The eye dropper tool is a native browser feature that allows a user pick a color from a current page's canvas. To support this, use the `getEyeDropperTriggerProps(...)`. > **Note:** The eye dropper tool only works in Chrome and Edge browsers ```html ``` ## Usage within forms To use the color picker within a form, add the `name` context property to the machine and render the visually hidden input using the `hiddenInputProps`. ```jsx {2} const service = useMachine(colorPicker.machine, { name: "color-preference", }) ``` ## Styling guide Each color picker part has a `data-part` attribute added to them to help you identify and style them easily. ### Open and closed state When the color picker is open or closed, the `data-state` attribute is added to the trigger, content, control parts. ```css [data-part="control"][data-state="open|closed"] { /* styles for control open or state */ } [data-part="trigger"][data-state="open|closed"] { /* styles for control open or state */ } [data-part="content"][data-state="open|closed"] { /* styles for control open or state */ } ``` ### Focused State When the color picker is focused, the `data-focus` attribute is added to the control and label parts. ```css [data-part="control"][data-focus] { /* styles for control focus state */ } [data-part="label"][data-focus] { /* styles for label focus state */ } ``` ### Disabled State When the color picker is disabled, the `data-disabled` attribute is added to the label, control, trigger and option parts. ```css [data-part="label"][data-disabled] { /* styles for label disabled state */ } [data-part="control"][data-disabled] { /* styles for control disabled state */ } [data-part="trigger"][data-disabled] { /* styles for trigger disabled state */ } [data-part="swatch-trigger"][data-disabled] { /* styles for item disabled state */ } ``` ### Swatch State When a swatch's color value matches the color picker's value, the `data-state=checked` attribute is added to the swatch part. ```css [data-part="swatch-trigger"][data-state="checked|unchecked"] { /* styles for swatch's checked state */ } ``` ## Methods and Properties ### Machine Context The color picker machine exposes the following context properties: **`ids`** Type: `Partial<{ root: string; control: string; trigger: string; label: string; input: string; hiddenInput: string; content: string; area: string; areaGradient: string; positioner: string; formatSelect: string; areaThumb: string; channelInput(id: string): string; channelSliderTrack(id: ColorChannel): string; }>` Description: The ids of the elements in the color picker.

**`Esc`** Description: Closes the color picker and moves focus to the trigger # Combobox A combobox is an input widget with an associated popup that enables users to select a value from a collection of possible values. ## Resources [Latest version: v1.7.0](https://www.npmjs.com/package/@zag-js/combobox) [Logic Visualizer](https://zag-visualizer.vercel.app/combobox) [Source Code](https://github.com/chakra-ui/zag/tree/main/packages/machines/combobox) **Features** - Support for selecting multiple values - Support for disabled options - Support for custom user input values - Support for mouse, touch, and keyboard interactions - Keyboard support for opening the combo box list box using the arrow keys, including automatically focusing the first or last item accordingly ## Installation To use the combobox machine in your project, run the following command in your command line: ```bash npm install @zag-js/combobox @zag-js/vue # or yarn add @zag-js/combobox @zag-js/vue ``` This command will install the framework agnostic combobox logic and the reactive utilities for your framework of choice. ## Anatomy To set up the combobox correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Usage First, import the combobox package into your project ```jsx import * as combobox from "@zag-js/combobox" ``` The combobox package exports these functions: - `machine` — The state machine logic for the combobox widget. - `connect` — The function that translates the machine's state to JSX attributes and event handlers. - `collection` - The function that creates a [collection interface](/overview/collection) from an array of items. Next, import the required hooks and functions for your framework and use the combobox machine in your project 🔥 ```html ``` ## Setting the initial value To set the initial value of the combobox, pass the `value` property to the machine's context. > The `value` property must be an array of strings. If selecting a single value, > pass an array with a single string. ```jsx {13} const collection = combobox.collection({ items: [ { label: "Nigeria", value: "ng" }, { label: "Ghana", value: "gh" }, { label: "Kenya", value: "ke" }, //... ], }) const service = useMachine(combobox.machine, { id: useId(), collection, defaultValue: ["ng"], }) ``` ## Selecting multiple values To allow selecting multiple values, set the `multiple` property in the machine's context to `true`. ```jsx {4} const service = useMachine(combobox.machine, { id: useId(), collection, multiple: true, }) ``` ## Using a custom object format By default, the combobox collection expects an array of items with `label` and `value` properties. To use a custom object format, pass the `itemToString` and `itemToValue` properties to the collection function. - `itemToString` — A function that returns the string representation of an item. Used to compare items when filtering. - `itemToValue` — A function that returns the unique value of an item. - `itemToDisabled` — A function that returns the disabled state of an item. ```jsx const collection = combobox.collection({ // custom object format items: [ { id: 1, fruit: "Banana", available: true, quantity: 10 }, { id: 2, fruit: "Apple", available: false, quantity: 5 }, { id: 3, fruit: "Orange", available: true, quantity: 3 }, //... ], // convert item to string itemToString(item) { return item.fruit }, // convert item to value itemToValue(item) { return item.id }, // convert item to disabled state itemToDisabled(item) { return !item.available || item.quantity === 0 }, }) // use the collection const service = useMachine(combobox.machine, { id: useId(), collection, }) ``` ## Rendering the selected values outside the combobox By default, the selected values of a combobox are displayed in the input element, when selecting multiple items, it is a better UX to render the selected value outside the combobox. To achieve this you need to: - Set the `selectionBehavior` to `clear`, which clears the input value when an item is selected. - Set the `multiple` property to `true` to allow selecting multiple values. - Render the selected values outside the combobox. ```jsx {4-6} const service = useMachine(combobox.machine, { id: useId(), collection, selectionBehavior: "clear", multiple: true, }) ``` ## Disabling the combobox To make a combobox disabled, set the context's `disabled` property to `true` ```jsx {2} const service = useMachine(combobox.machine, { disabled: true, }) ``` ## Disabling an option To make a combobox option disabled, pass the `isItemDisabled` property to the collection function. ```jsx {6-8} const service = useMachine(combobox.machine, { id: useId(), collection: combobox.collection({ items: countries, isItemDisabled(item) { return item.disabled }, }), }) ``` ## Close on select This behaviour ensures that the menu is closed when an option is selected and is `true` by default. It's only concerned with when an option is selected with pointer or enter key. To disable the behaviour, set the `closeOnSelect` property in the machine's context to `false`. ```jsx {2} const service = useMachine(combobox.machine, { closeOnSelect: false, }) ``` ## Making the combobox readonly To make a combobox readonly, set the context's `readOnly` property to `true` ```jsx {2} const service = useMachine(combobox.machine, { readOnly: true, }) ``` ## Listening for highlight changes When an option is highlighted with the pointer or keyboard, use the `onHighlightChange` property to listen for this change and do something with it. ```jsx {3-6} const service = useMachine(combobox.machine, { id: useId(), onHighlightChange(details) { // details => { value: string | null; item: CollectionItem | null } console.log(details) }, }) ``` ## Listening for value changes When an item is selected, use `onValueChange` property to listen for this change and do something with it. ```jsx {3-6} const service = useMachine(combobox.machine, { onValueChange(details) { // details => { value: string[]; items: CollectionItem[] } console.log(details) }, }) ``` ## Usage within forms The combobox works when placed within a form and the form is submitted. We achieve this by: - ensuring we emit the input event as the value changes. - adding a `name` attribute to the input so the value can be accessed in the `FormData`. To get this feature working you need to pass a `name` option to the context. ```jsx {2} const service = useMachine(combobox.machine, { name: "countries", }) ``` ## Allowing custom values By default, the combobox only allows selecting values from the collection. To allow custom values, set the `allowCustomValue` property in the machine's context to `true`. ```jsx {2} const service = useMachine(combobox.machine, { allowCustomValue: true, }) ``` ## Styling guide Earlier, we mentioned that each combobox part has a `data-part` attribute added to them to select and style them in the DOM. ### Open and closed state When the combobox is open or closed, the `data-state` attribute is added to the content,control, input and control parts. ```css [data-part="control"][data-state="open|closed"] { /* styles for control open or state */ } [data-part="input"][data-state="open|closed"] { /* styles for control open or state */ } [data-part="trigger"][data-state="open|closed"] { /* styles for control open or state */ } [data-part="content"][data-state="open|closed"] { /* styles for control open or state */ } ``` ### Focused State When the combobox is focused, the `data-focus` attribute is added to the control and label parts. ```css [data-part="control"][data-focus] { /* styles for control focus state */ } [data-part="label"][data-focus] { /* styles for label focus state */ } ``` ### Disabled State When the combobox is disabled, the `data-disabled` attribute is added to the label, control, trigger and option parts. ```css [data-part="label"][data-disabled] { /* styles for label disabled state */ } [data-part="control"][data-disabled] { /* styles for control disabled state */ } [data-part="trigger"][data-disabled] { /* styles for trigger disabled state */ } [data-part="item"][data-disabled] { /* styles for item disabled state */ } ``` ### Invalid State When the combobox is invalid, the `data-invalid` attribute is added to the root, label, control and input parts. ```css [data-part="root"][data-invalid] { /* styles for root invalid state */ } [data-part="label"][data-invalid] { /* styles for label invalid state */ } [data-part="control"][data-invalid] { /* styles for control invalid state */ } [data-part="input"][data-invalid] { /* styles for input invalid state */ } ``` ### Selected State When a combobox item is selected, the `data-selected` attribute is added to the item part. ```css [data-part="item"][data-state="checked|unchecked"] { /* styles for item selected state */ } ``` ### Highlighted State When a combobox item is highlighted, the `data-highlighted` attribute is added to the item part. ```css [data-part="item"][data-highlighted] { /* styles for item highlighted state */ } ``` ## Methods and Properties ### Machine Context The combobox machine exposes the following context properties: **`open`** Type: `boolean` Description: The controlled open state of the combobox **`defaultOpen`** Type: `boolean` Description: The initial open state of the combobox when rendered.

This function uses [`@internationalized/date`](https://react-spectrum.adobe.com/internationalized/date/CalendarDate.html) under the hood. > You'll also need to provide a unique `id` to the `useMachine` hook. This is > used to ensure that every part has a unique identifier. Next, import the required hooks and functions for your framework and use the date-picker machine in your project 🔥 ```html ``` ## Setting the initial date To set the initial value that is rendered by the date picker, set the `value` property in the machine context. ```jsx const service = useMachine(datepicker.machine, { defaultValue: [datepicker.parse("2022-01-01")], }) ``` ## Controlling the selected date Use the `api.setValue` method to control the selected date in the DatePicker component. ```jsx // parse the date string into a date object const nextValue = datepicker.parse("2022-01-01") // set the new value api.setValue(nextValue) ``` > Alternatively, you can also use the `value` and `onValueChange` callbacks to > programmatically control the selected date. ## Controlling the open state To manage the open state of the datepicker's dialog, we recommended using `api.setOpen` method. ```jsx // open the date picker api.setOpen(true) // close the date picker api.setOpen(false) ``` > Alternatively, you can also use the `open` and `onOpenChange` callbacks to > programmatically control the open state. ## Setting the min and max dates To constrain the date range that can be selected by the user, set the `min` and `max` properties in the machine context. ```jsx const service = useMachine(datepicker.machine, { min: datepicker.parse("2022-01-01"), max: datepicker.parse("2022-12-31"), }) ``` When the min or max date value is reached, the next and prev triggers will be disabled. ## Changing the start of the week Set the `startOfWeek` property in the machine context to change the start of the week. The property accepts a number from `0` to `6`, where `0` is Sunday and `6` is Saturday. ```jsx const service = useMachine(datepicker.machine, { startOfWeek: 1, // Monday }) ``` ## Disabling the date picker To disable the date picker, set the `disabled` property in the machine context to `true`. ```jsx const service = useMachine(datepicker.machine, { disabled: true, }) ``` ## Rendering month and year pickers To render the month and year pickers, use the `api.getMonthSelectProps` and `api.getYearSelectProps` prop getters. ```jsx
``` ## Marking unavailable dates To mark specific dates as unavailable, set the `isDateUnavailable` function in the machine context. This function should return `true` for dates that are unavailable. ```jsx const service = useMachine(datepicker.machine, { isDateUnavailable: (date, locale) => { // mark weekends as unavailable return date.day === 0 || date.day === 6 }, }) ``` You can also leverage the numerous helpers from [`@internationalized/date`](https://react-spectrum.adobe.com/internationalized/date/CalendarDate.html) to create more complex date availability rules. ```jsx import { isWeekend } from "@internationalized/date" const service = useMachine(datepicker.machine, { isDateUnavailable: (date, locale) => { // mark weekends as unavailable return isWeekend(date, locale) }, }) ``` ## Setting the calendar starting view The calendar view is set to `day` by default. To change the starting view of the calendar, set the `view` property in the machine context to either `day`, `month`, or `year`. ```jsx const service = useMachine(datepicker.machine, { view: "month", }) ``` ## Setting the read-only mode Set the `readOnly` property in the machine context to `true` to make the date picker read-only. This means that users can't change the selected date. ```jsx const service = useMachine(datepicker.machine, { readOnly: true, }) ``` ## Setting the focused date The datepicker's focused date is set to either the first selected date or today's date by default. To change the focused date, set the `focusedDate` property in the machine context. ```jsx const service = useMachine(datepicker.machine, { focusedDate: datepicker.parse("2022-01-01"), }) ``` ## Rendering the calendar inline To render the calendar inline, we recommended setting the `open` property to `true` and `closeOnSelect` to `false`. ```jsx const service = useMachine(datepicker.machine, { open: true, closeOnSelect: false, }) ``` ## Usage within a form To use the date picker within a form, set the `name` property in the machine context. This property is used to identify the date picker in the form data. ```jsx const service = useMachine(datepicker.machine, { name: "date", }) ``` ## Rendering fixed number of weeks The datepicker's calendar will render the weeks needed to display all of the days in the month. Sometimes this can result in a jump in the UI when navigating between different sized months (e.g., February vs. March). To ensure the calendar renders the maximum number of weeks (6), you can set the `fixedWeeks` prop to `true`. ```jsx const service = useMachine(datepicker.machine, { fixedWeeks: true, }) ``` ## Listening to date changes To listen to date changes, use the `onValueChange` callback in the machine context. ```jsx const service = useMachine(datepicker.machine, { onValueChange(details) { // details => { value: DateValue[], valueAsString: string[], view: string } console.log("selected date:", details.valueAsString) }, }) ``` ## Listening to view changes When the calendar view changes by click on the view controls, the `onViewChange` callback is invoked. ```jsx const service = useMachine(datepicker.machine, { onViewChange(details) { // details => { view: string } console.log("view changed to:", details.view) }, }) ``` ## Styling guide Earlier, we mentioned that each date-picker part has a `data-part` attribute added to them to select and style them in the DOM. ```css [data-scope="date-picker"][data-part="root"] { /* styles for the root part */ } [data-scope="date-picker"][data-part="input"] { /* styles for the input part */ } [data-scope="date-picker"][data-part="trigger"] { /* styles for the trigger part */ } [data-scope="date-picker"][data-part="content"] { /* styles for the input part */ } ``` ### Open State ```css [data-scope="date-picker"][data-part="trigger"] { &[data-state="open"] { /* styles for the open state */ } &[data-state="closed"] { /* styles for the closed state */ } } ``` ### Cell States ```css [data-scope="date-picker"][data-part="table-cell-trigger"] { /* styles for the cell */ &[data-selected] { /* styles for the selected date */ } &[data-focus] { /* styles for the focused date */ } &[data-disabled] { /* styles for the disabled date */ } &[data-unavailable] { /* styles for the unavailable date */ } &[data-today] { /* styles for the today date */ } &[data-weekend] { /* styles for the weekend date */ } } ``` ## Methods and Properties ### Machine Context The date picker machine exposes the following context properties: **`locale`** Type: `string` Description: The locale (BCP 47 language tag) to use when formatting the date. **`translations`** Type: `IntlTranslations` Description: The localized messages to use. **`ids`** Type: `Partial<{ root: string; label(index: number): string; table(id: string): string; tableHeader(id: string): string; tableBody(id: string): string; tableRow(id: string): string; content: string; cellTrigger(id: string): string; prevTrigger(view: DateView): string; clearTrigger: string; control: string; input(index: number): string; trigger: string; monthSelect: string; yearSelect: string; positioner: string; }>` Description: The ids of the elements in the date picker.

Content behind a modal dialog is inert, meaning that users cannot interact with it. ## Resources [Latest version: v1.7.0](https://www.npmjs.com/package/@zag-js/dialog) [Logic Visualizer](https://zag-visualizer.vercel.app/dialog) [Source Code](https://github.com/chakra-ui/zag/tree/main/packages/machines/dialog) **Features** - Supports modal and non-modal modes. - Focus is trapped and scrolling is blocked in the modal mode. - Provides screen reader announcements via rendered title and description. - Pressing `Esc` closes the dialog. ## Installation To use the dialog machine in your project, run the following command in your command line: ```bash npm install @zag-js/dialog @zag-js/vue # or yarn add @zag-js/dialog @zag-js/vue ``` This command will install the framework agnostic dialog logic and the reactive utilities for your framework of choice. ## Anatomy To use the dialog component correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Usage First, import the dialog package into your project ```jsx import * as dialog from "@zag-js/dialog" ``` The dialog package exports two key functions: - `machine` — The state machine logic for the dialog widget as described in WAI-ARIA specification. - `connect` — The function that translates the machine's state to JSX attributes and event handlers. > You'll need to provide a unique `id` to the `useMachine` hook. This is used to > ensure that every part has a unique identifier. Next, import the required hooks and functions for your framework and use the dialog machine in your project 🔥 ```html ``` ## Managing focus within the dialog When the dialog opens, it automatically sets focus on the first focusable elements and traps focus within it, so that tabbing is constrained to it. To control the element that should receive focus on open, pass the `initialFocusEl` context (which can be an element or a function that returns an element) ```html {5,10,16} ``` To set the element that receives focus when the dialog closes, pass the `finalFocusEl` in the similar fashion as shown above. ## Closing the dialog on interaction outside By default, the dialog closes when you click its overlay. You can set `closeOnInteractOutside` to `false` if you want the modal to stay visible. ```jsx {2} const service = useMachine(dialog.machine, { closeOnInteractOutside: false, }) ``` You can also customize the behavior by passing a function to the `onInteractOutside` context and calling `event.preventDefault()` ```jsx {2-7} const service = useMachine(dialog.machine, { onInteractOutside(event) { const target = event.target if (target?.closest("")) { return event.preventDefault() } }, }) ``` ## Listening for open state changes When the dialog is opened or closed, the `onOpenChange` callback is invoked. ```jsx {2-7} const service = useMachine(dialog.machine, { onOpenChange(details) { // details => { open: boolean } console.log("open:", details.open) }, }) ``` ## Controlling the scroll behavior When the dialog is open, it prevents scrolling on the `body` element. To disable this behavior, set the `preventScroll` context to `false`. ```jsx {2} const service = useMachine(dialog.machine, { preventScroll: false, }) ``` ## Creating an alert dialog The dialog has support for dialog and alert dialog roles. It's set to `dialog` by default. To change it's role, pass the `role: alertdialog` property to the machine's context. That's it! Now you have an alert dialog. ```jsx {2} const service = useMachine(dialog.machine, { role: "alertdialog", }) ``` > By definition, an alert dialog will contain two or more action buttons. We > recommended setting focus to the least destructive action via `initialFocusEl` ## Styling guide Earlier, we mentioned that each accordion part has a `data-part` attribute added to them to select and style them in the DOM. ```css [data-part="trigger"] { /* styles for the trigger element */ } [data-part="backdrop"] { /* styles for the backdrop element */ } [data-part="positioner"] { /* styles for the positioner element */ } [data-part="content"] { /* styles for the content element */ } [data-part="title"] { /* styles for the title element */ } [data-part="description"] { /* styles for the description element */ } [data-part="close-trigger"] { /* styles for the close trigger element */ } ``` ### Open and closed state The dialog has two states: `open` and `closed`. You can use the `data-state` attribute to style the dialog or trigger based on its state. ```css [data-part="content"][data-state="open|closed"] { /* styles for the open state */ } [data-part="trigger"][data-state="open|closed"] { /* styles for the open state */ } ``` ## Methods and Properties ### Machine Context The dialog machine exposes the following context properties: **`ids`** Type: `Partial<{ trigger: string; positioner: string; backdrop: string; content: string; closeTrigger: string; title: string; description: string; }>` Description: The ids of the elements in the dialog. Useful for composition. **`trapFocus`** Type: `boolean` Description: Whether to trap focus inside the dialog when it's opened **`preventScroll`** Type: `boolean` Description: Whether to prevent scrolling behind the dialog when it's opened **`modal`** Type: `boolean` Description: Whether to prevent pointer interaction outside the element and hide all content below it **`initialFocusEl`** Type: `() => HTMLElement` Description: Element to receive focus when the dialog is opened **`finalFocusEl`** Type: `() => HTMLElement` Description: Element to receive focus when the dialog is closed **`restoreFocus`** Type: `boolean` Description: Whether to restore focus to the element that had focus before the dialog was opened **`closeOnInteractOutside`** Type: `boolean` Description: Whether to close the dialog when the outside is clicked **`closeOnEscape`** Type: `boolean` Description: Whether to close the dialog when the escape key is pressed **`aria-label`** Type: `string` Description: Human readable label for the dialog, in event the dialog title is not rendered **`role`** Type: `"dialog" | "alertdialog"` Description: The dialog's role **`open`** Type: `boolean` Description: The controlled open state of the dialog **`defaultOpen`** Type: `boolean` Description: The initial open state of the dialog when rendered. Use when you don't need to control the open state of the dialog. **`onOpenChange`** Type: `(details: OpenChangeDetails) => void` Description: Function to call when the dialog's open state changes **`dir`** Type: `"ltr" | "rtl"` Description: The document's text/writing direction. **`id`** Type: `string` Description: The unique identifier of the machine. **`getRootNode`** Type: `() => Node | ShadowRoot | Document` Description: A root node to correctly resolve document in custom environments. E.x.: Iframes, Electron. **`onEscapeKeyDown`** Type: `(event: KeyboardEvent) => void` Description: Function called when the escape key is pressed **`onPointerDownOutside`** Type: `(event: PointerDownOutsideEvent) => void` Description: Function called when the pointer is pressed down outside the component **`onFocusOutside`** Type: `(event: FocusOutsideEvent) => void` Description: Function called when the focus is moved outside the component **`onInteractOutside`** Type: `(event: InteractOutsideEvent) => void` Description: Function called when an interaction happens outside the component **`persistentElements`** Type: `(() => Element)[]` Description: Returns the persistent elements that: - should not have pointer-events disabled - should not trigger the dismiss event ### Machine API The dialog `api` exposes the following methods: **`open`** Type: `boolean` Description: Whether the dialog is open **`setOpen`** Type: `(open: boolean) => void` Description: Function to open or close the dialog ### Data Attributes **`Trigger`** **`data-scope`**: dialog **`data-part`**: trigger **`data-state`**: "open" | "closed" **`Backdrop`** **`data-scope`**: dialog **`data-part`**: backdrop **`data-state`**: "open" | "closed" **`Content`** **`data-scope`**: dialog **`data-part`**: content **`data-state`**: "open" | "closed" ## Accessibility Adheres to the [Alert and Message Dialogs WAI-ARIA design pattern](https://www.w3.org/WAI/ARIA/apg/patterns/alertdialog). ### Keyboard Interactions **`Enter`** Description: When focus is on the trigger, opens the dialog. **`Tab`** Description: Moves focus to the next focusable element within the content. Focus is trapped within the dialog. **`Shift + Tab`** Description: Moves focus to the previous focusable element. Focus is trapped within the dialog. **`Esc`** Description: Closes the dialog and moves focus to trigger or the defined final focus element # Editable Editable is an input field used for editing a single line of text. It renders as static text and transforms into a text input field when then edit interaction is triggered (click, focus, or double-click). ## Resources [Latest version: v1.7.0](https://www.npmjs.com/package/@zag-js/editable) [Logic Visualizer](https://zag-visualizer.vercel.app/editable) [Source Code](https://github.com/chakra-ui/zag/tree/main/packages/machines/editable) **Features** - Use custom controls for the editable. - Pressing `Enter` commits the input value. - Pressing `Esc` reverts the value. - Activate edit mode by double-clicking or focusing on the preview text. - Auto-resize input to fit content ## Installation To use the editable machine in your project, run the following command in your command line: ```bash npm install @zag-js/editable @zag-js/vue # or yarn add @zag-js/editable @zag-js/vue ``` This command will install the framework agnostic editable logic and the reactive utilities for your framework of choice. ## Anatomy To set up the editable correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Usage First, import the editable package into your project ```jsx import * as editable from "@zag-js/editable" ``` The editable package exports two key functions: - `machine` — The state machine logic for the editable widget. - `connect` — The function that translates the machine's state to JSX attributes and event handlers. > You'll need to provide a unique `id` to the `useMachine` hook. This is used to > ensure that every part has a unique identifier. Next, import the required hooks and functions for your framework and use the editable machine in your project 🔥 ```html ``` ## Setting the initial value To set the initial value of the editable, pass the `value` property to the machine's context. ```jsx {2} const service = useMachine(editable.machine, { defaultValue: "Hello World", }) ``` ## Listening for value changes The editable machine supports two ways of listening for value changes: - `onValueChange`: called when value changes. - `onValueCommit`: called when the value is committed. ```jsx {2-4} const service = useMachine(editable.machine, { onValueChange(details) { console.log("Value changed", details.value) }, onValueCommit(details) { console.log("Value submitted", details.value) }, }) ``` ## Using custom controls In some cases, you might need to use custom controls to toggle the edit and read mode. We use the render prop pattern to provide access to the internal state of the component. ```html ``` ## Auto-resizing the editable To auto-grow the editable as the content changes, pass the `autoResize: true` property to the machine's context. ```jsx {2} const service = useMachine(editable.machine, { autoResize: true, }) ``` When using autoresize, the input and preview elements should not have any styles. Use `all: unset` if needed and pass any styles to the "area" element since its shared by the input and preview elements. ### Setting a maxWidth It is a common pattern to set a maximum of the editable as it auto-grows. To achieve this, set the `maxWidth` property of the machine's context to the desired value. ```jsx {2-3} const service = useMachine(editable.machine, { autoResize: true, maxWidth: "320px", }) ``` When the editable reaches the specified max-width, it'll clip the preview text with an ellipsis. ## Editing with double click The editable supports two modes of activating the "edit" state: - when the preview part is focused (with pointer or keyboard). - when the preview part is double-clicked. To change the mode to "double-click", set the `activationMode: 'dblclick'` property in the machine's context. ```jsx {2} const service = useMachine(editable.machine, { activationMode: "dblclick", }) ``` ## Usage with Textarea The editable machine supports using a `textarea` instead of an `input` field. When a textarea is used, the editable will commit the value on `Cmd + Enter` or `Ctrl + Enter`. > Use the `api.inputProps` to spread the input props to the textarea element. > You might need to cast the input props to the correct type. ```tsx {2}
