# Grid

<blockquote experimental="true">

  **This is experimental** and may introduce **breaking changes** or be **removed altogether** in patch and minor versions without notice. Learn more in [Experimental features](/docs/experimental/).

</blockquote>

Accessible `Grid` component that enables users to navigate the information or interactive elements it contains using directional navigation keys. The items are organized in a two-dimensional container. It follows the [WAI-ARIA Grid Pattern](https://www.w3.org/TR/wai-aria-practices/#grid).

## Accessibility

- `Grid` has role `grid`.
- `Grid` extends the accessibility features of [Composite](/docs/composite/#accessibility).
- `GridRow` has role `row`.
- `GridRow` extends the accessibility features of [CompositeGroup](/docs/composite/#accessibility).
- `GridCell` has role `gridcell`.
- `GridCell` extends the accessibility features of [CompositeItem](/docs/composite/#accessibility).

Learn more in [Accessibility](/docs/accessibility/).

## Composition

- `Grid` uses [Composite](/docs/composite/).
- `GridRow` uses [CompositeGroup](/docs/composite/).
- `GridCell` uses [CompositeItem](/docs/composite/).

## Props

<!-- Automatically generated -->

### `useGridState`

- **`baseId`**
  <code>string</code>

  ID that will serve as a base for all the items IDs.

- **`unstable_virtual`** <span title="Experimental">⚠️</span>
  <code>boolean</code>

  If enabled, the composite element will act as an
[aria-activedescendant](https://www.w3.org/TR/wai-aria-practices-1.1/#kbd_focus_activedescendant)
container instead of
[roving tabindex](https://www.w3.org/TR/wai-aria-practices/#kbd_roving_tabindex).
DOM focus will remain on the composite while its items receive virtual focus.

- **`rtl`**
  <code>boolean</code>

  Determines how `next` and `previous` functions will behave. If `rtl` is
set to `true`, they will be inverted. This only affects the composite
widget behavior. You still need to set `dir="rtl"` on HTML/CSS.

- **`orientation`**
  <code>&#34;horizontal&#34; | &#34;vertical&#34; | undefined</code>

  Defines the orientation of the composite widget. If the composite has a
single row or column (one-dimensional), the `orientation` value determines
which arrow keys can be used to move focus:
  - `undefined`: all arrow keys work.
  - `horizontal`: only left and right arrow keys work.
  - `vertical`: only up and down arrow keys work.

  It doesn't have any effect on two-dimensional composites.

- **`currentId`**
  <code>string | null | undefined</code>

  The current focused item `id`.
  - `undefined` will automatically focus the first enabled composite item.
  - `null` will focus the base composite element and users will be able to
navigate out of it using arrow keys.
  - If `currentId` is initially set to `null`, the base composite element
itself will have focus and users will be able to navigate to it using
arrow keys.

- **`loop`**
  <code>boolean | &#34;horizontal&#34; | &#34;vertical&#34;</code>

  On one-dimensional composites:
  - `true` loops from the last item to the first item and vice-versa.
  - `horizontal` loops only if `orientation` is `horizontal` or not set.
  - `vertical` loops only if `orientation` is `vertical` or not set.
  - If `currentId` is initially set to `null`, the composite element will
be focused in between the last and first items.

  On two-dimensional composites:
  - `true` loops from the last row/column item to the first item in the
same row/column and vice-versa. If it's the last item in the last row, it
moves to the first item in the first row and vice-versa.
  - `horizontal` loops only from the last row item to the first item in
the same row.
  - `vertical` loops only from the last column item to the first item in
the column row.
  - If `currentId` is initially set to `null`, vertical loop will have no
effect as moving down from the last row or up from the first row will
focus the composite element.
  - If `wrap` matches the value of `loop`, it'll wrap between the last
item in the last row or column and the first item in the first row or
column and vice-versa.

- **`wrap`**
  <code>boolean | &#34;horizontal&#34; | &#34;vertical&#34;</code>

  **Has effect only on two-dimensional composites**. If enabled, moving to
the next item from the last one in a row or column will focus the first
item in the next row or column and vice-versa.
  - `true` wraps between rows and columns.
  - `horizontal` wraps only between rows.
  - `vertical` wraps only between columns.
  - If `loop` matches the value of `wrap`, it'll wrap between the last
item in the last row or column and the first item in the first row or
column and vice-versa.

- **`shift`**
  <code>boolean</code>

  **Has effect only on two-dimensional composites**. If enabled, moving up
or down when there's no next item or the next item is disabled will shift
to the item right before it.

### `Grid`

- **`disabled`**
  <code>boolean | undefined</code>

  Same as the HTML attribute.

- **`focusable`**
  <code>boolean | undefined</code>

  When an element is `disabled`, it may still be `focusable`. It works
similarly to `readOnly` on form elements. In this case, only
`aria-disabled` will be set.

<details><summary>12 state props</summary>

> These props are returned by the state hook. You can spread them into this component (`{...state}`) or pass them separately. You can also provide these props from your own state logic.

- **`baseId`**
  <code>string</code>

  ID that will serve as a base for all the items IDs.

- **`unstable_virtual`** <span title="Experimental">⚠️</span>
  <code>boolean</code>

  If enabled, the composite element will act as an
[aria-activedescendant](https://www.w3.org/TR/wai-aria-practices-1.1/#kbd_focus_activedescendant)
container instead of
[roving tabindex](https://www.w3.org/TR/wai-aria-practices/#kbd_roving_tabindex).
DOM focus will remain on the composite while its items receive virtual focus.

- **`orientation`**
  <code>&#34;horizontal&#34; | &#34;vertical&#34; | undefined</code>

  Defines the orientation of the composite widget. If the composite has a
single row or column (one-dimensional), the `orientation` value determines
which arrow keys can be used to move focus:
  - `undefined`: all arrow keys work.
  - `horizontal`: only left and right arrow keys work.
  - `vertical`: only up and down arrow keys work.

  It doesn't have any effect on two-dimensional composites.

- **`currentId`**
  <code>string | null | undefined</code>

  The current focused item `id`.
  - `undefined` will automatically focus the first enabled composite item.
  - `null` will focus the base composite element and users will be able to
navigate out of it using arrow keys.
  - If `currentId` is initially set to `null`, the base composite element
itself will have focus and users will be able to navigate to it using
arrow keys.

- **`wrap`**
  <code>boolean | &#34;horizontal&#34; | &#34;vertical&#34;</code>

  **Has effect only on two-dimensional composites**. If enabled, moving to
the next item from the last one in a row or column will focus the first
item in the next row or column and vice-versa.
  - `true` wraps between rows and columns.
  - `horizontal` wraps only between rows.
  - `vertical` wraps only between columns.
  - If `loop` matches the value of `wrap`, it'll wrap between the last
item in the last row or column and the first item in the first row or
column and vice-versa.

- **`unstable_moves`** <span title="Experimental">⚠️</span>
  <code>number</code>

  Stores the number of moves that have been performed by calling `move`,
`next`, `previous`, `up`, `down`, `first` or `last`.

- **`groups`**
  <code>Group[]</code>

  Lists all the composite groups with their `id` and DOM `ref`. This state
is automatically updated when `registerGroup` and `unregisterGroup` are
called.

- **`items`**
  <code>Item[]</code>

  Lists all the composite items with their `id`, DOM `ref`, `disabled` state
and `groupId` if any. This state is automatically updated when
`registerItem` and `unregisterItem` are called.

- **`setCurrentId`**
  <code title="(value: SetStateAction&#60;string | null | undefined&#62;) =&#62; void">(value: SetStateAction&#60;string | null | undefine...</code>

  Sets `currentId`. This is different from `composite.move` as this only
updates the `currentId` state without moving focus. When the composite
widget gets focused by the user, the item referred by the `currentId`
state will get focus.

- **`first`**
  <code>() =&#62; void</code>

  Moves focus to the first item.

- **`last`**
  <code>() =&#62; void</code>

  Moves focus to the last item.

- **`move`**
  <code>(id: string | null) =&#62; void</code>

  Moves focus to a given item ID.
