RadioProvider

Provides a radio store to Radio components.

Code examples

<RadioProvider defaultValue="Apple">
  <RadioGroup>
    <Radio value="Apple" />
    <Radio value="Orange" />
  </RadioGroup>
</RadioProvider>
<RadioProvider defaultValue="Apple">
  <RadioGroup>
    <Radio value="Apple" />
    <Radio value="Orange" />
  </RadioGroup>
</RadioProvider>

Optional Props

`activeId`

string | null | undefined
string | null | undefined

The current active item id. The active item is the element within the composite widget that has either DOM or virtual focus (in case virtualFocus is enabled).

null represents the base composite element (the one with a composite role⁠). Users will be able to navigate out of it using arrow keys.
If activeId is initially set to null, the includesBaseElement prop will also default to true, which means the base composite element itself will have focus and users will be able to navigate to it using arrow keys.

`defaultActiveId`

string | null | undefined
string | null | undefined

The composite item id that should be active by default when the composite widget is rendered. If null, the composite element itself will have focus and users will be able to navigate to it using arrow keys. If undefined, the first enabled item will be focused.

`defaultItems`

T[] | undefined = []
T[] | undefined = []

The defaut value for the items state.

`defaultValue`

string | number | null | undefined = null
string | number | null | undefined = null

The default value of the radio group.

`focusLoop`

boolean | Orientation = true
boolean | Orientation = true

Determines how the focus behaves when the user reaches the end of the composite widget.

On one-dimensional composite widgets:

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 includesBaseElement is set to true (or activeId is initially set to null), the composite element will be focused in between the last and first items.

On two-dimensional composite widgets (when using CompositeRow or explicitly passing a rowId prop to composite items):

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 includesBaseElement is set to true (or activeId 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 on the composite element.
If focusWrap matches the value of focusLoop, 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.

`focusShift`

boolean = false
boolean = false

Works only on two-dimensional composite widgets.

If enabled, moving up or down when there's no next item or when the next item is disabled will shift to the item right before it.

`focusWrap`

boolean | Orientation = false
boolean | Orientation = false

Works only on two-dimensional composite widgets.

If enabled, moving to the next item from the last one in a row or column will focus on 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 focusLoop matches the value of focusWrap, 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.

`id`

string
string

The ID of the composite store is used to reference elements within the composite widget before hydration. If not provided, a random ID will be generated.

`includesBaseElement`

boolean = false
boolean = false

Indicates if the composite base element (the one with a composite role⁠) should be part of the focus order when navigating with arrow keys. In other words, moving to the previous element when the first item is in focus will focus on the composite element itself. The same applies to the last item when moving to the next element.

`items`

T[]
T[]

Lists all items along with their metadata. This state is automatically updated when an item is registered or unregistered using the registerItem function.

`orientation`

Orientation = "both"
Orientation = "both"

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:

both: 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.

`rtl`

boolean = false
boolean = false

Determines how the 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.

`setActiveId`

((activeId: string | null | undefined) => void) | undefined
((activeId: string | null | undefined) => void) | undefined

A callback that gets called when the activeId state changes.

`setItems`

BivariantCallback<(items: T[]) => void> | undefined
BivariantCallback<(items: T[]) => void> | undefined

A callback that gets called when the items state changes.

Code examples

const [items, setItems] = useState([]);
const collection = useCollectionStore({ items, setItems });
const [items, setItems] = useState([]);
const collection = useCollectionStore({ items, setItems });

`setValue`

((value: string | number | null) => void) | undefined
((value: string | number | null) => void) | undefined

Function that will be called when the value state changes.

`store`

Store<Partial<S>> | undefined
Store<Partial<S>> | undefined

Another store object that will be kept in sync with the original store.

Live examples

`value`

string | number | null = null
string | number | null = null

The value of the radio group.

`virtualFocus`

boolean = false
boolean = false

If enabled, the composite element will act as an aria-activedescendant⁠ container instead of roving tabindex⁠. DOM focus will remain on the composite element while its items receive virtual focus.

In both scenarios, the item in focus will carry the data-active-item attribute.
