Combobox

Combobox properties
Prop	Type	Default	Description
`form`	string \| undefined string \| undefined	`—`	Identifies the form that owns the internal input. Useful when the combobox is rendered outside the form.
`filter`	((itemValue: Value, query: string, itemToString?: ((itemValue: Value) => string) \| undefin… ((itemValue: Value, query: string, itemToString?: ((itemValue: Value) => string) \| undefined) => boolean) \| null \| undefined	`—`	Filter function used to match items vs input query.
`id`	string \| undefined string \| undefined	`—`	The id of the component.
`children`	React.ReactNode React.ReactNode	`—`	Content rendered inside this component.
`disabled`	boolean \| undefined boolean \| undefined	`false`	Whether the component should ignore user interaction.
`name`	string \| undefined string \| undefined	`—`	Identifies the field when a form is submitted.
`modal`	boolean \| undefined boolean \| undefined	`false`	Determines if the popup enters a modal state when open. - `true`: user interaction is limited to the popup: document page scroll is locked and pointer interactions on outside elements are disabled. - `false`: user interaction with the rest of the document is allowed.
`open`	boolean \| undefined boolean \| undefined	`—`	Whether the popup is currently open. Use when controlled.
`defaultOpen`	boolean \| undefined boolean \| undefined	`false`	Whether the popup is initially open. To render a controlled popup, use the `open` prop instead.
`onOpenChangeComplete`	((open: boolean) => void) \| undefined ((open: boolean) => void) \| undefined	`—`	Event handler called after any animations complete when the popup is opened or closed.
`inline`	boolean \| undefined boolean \| undefined	`false`	Whether the list is rendered inline without using the popup.
`grid`	boolean \| undefined boolean \| undefined	`false`	Whether list items are presented in a grid layout. When enabled, arrow keys navigate across rows and columns inferred from DOM rows.
`required`	boolean \| undefined boolean \| undefined	`false`	Whether the user must choose a value before submitting a form.
`readOnly`	boolean \| undefined boolean \| undefined	`false`	Whether the user should be unable to choose a different option from the popup.
`openOnInputClick`	boolean \| undefined boolean \| undefined	`true`	Whether the popup opens when clicking the input.
`loopFocus`	boolean \| undefined boolean \| undefined	`true`	Whether to loop keyboard focus back to the input when the end of the list is reached while using the arrow keys. The first item can then be reached by pressing <kbd>ArrowDown</kbd> again from the input, or the last item can be reached by pressing <kbd>ArrowUp</kbd> from the input. The input is always included in the focus loop per [ARIA Authoring Practices](https://www.w3.org/WAI/ARIA/apg/patterns/combobox/). When disabled, focus does not move when on the last element and the user presses <kbd>ArrowDown</kbd>, or when on the first element and the user presses <kbd>ArrowUp</kbd>.
`inputValue`	string \| number \| readonly string[] \| undefined string \| number \| readonly string[] \| undefined	`—`	The input value of the combobox. Use when controlled.
`defaultInputValue`	string \| number \| readonly string[] \| undefined string \| number \| readonly string[] \| undefined	`—`	The uncontrolled input value when initially rendered. To render a controlled input, use the `inputValue` prop instead.
`inputRef`	React.Ref<HTMLInputElement> \| undefined React.Ref<HTMLInputElement> \| undefined	`—`	A ref to the hidden input element.
`items`	readonly any[] \| readonly Group<any>[] \| undefined readonly any[] \| readonly Group<any>[] \| undefined	`—`	The items to be displayed in the list. Can be either a flat array of items or an array of groups with items.
`filteredItems`	readonly any[] \| readonly Group<any>[] \| undefined readonly any[] \| readonly Group<any>[] \| undefined	`—`	Filtered items to display in the list. When provided, the list will use these items instead of filtering the `items` prop internally. Use when you want to control filtering logic externally with the `useFilter()` hook.
`virtualized`	boolean \| undefined boolean \| undefined	`false`	Whether the items are being externally virtualized.
`limit`	number \| undefined number \| undefined	`-1`	The maximum number of items to display in the list.

`autoComplete`	string \| undefined string \| undefined	`—`	Provides a hint to the browser for autofill.
`autoHighlight`	boolean \| undefined boolean \| undefined	`false`	Whether the first matching item is highlighted automatically while filtering.
`highlightItemOnHover`	boolean \| undefined boolean \| undefined	`true`	Whether moving the pointer over items should highlight them. Disabling this prop allows CSS `:hover` to be differentiated from the `:focus` (`data-highlighted`) state.
`itemToStringLabel`	((itemValue: Value) => string) \| undefined ((itemValue: Value) => string) \| undefined	`—`	When the item values are objects (`<Combobox.Item value={object}>`), this function converts the object value to a string representation for display in the input. If the shape of the object is `{ value, label }`, the label will be used automatically without needing to specify this prop.
`itemToStringValue`	((itemValue: Value) => string) \| undefined ((itemValue: Value) => string) \| undefined	`—`	When the item values are objects (`<Combobox.Item value={object}>`), this function converts the object value to a string representation for form submission.

`isItemEqualToValue`	((itemValue: Value, value: Value) => boolean) \| undefined ((itemValue: Value, value: Value) => boolean) \| undefined	`—`	Custom comparison logic used to determine if a combobox item value matches the current selected value. Useful when item values are objects without matching referentially. Defaults to `Object.is` comparison.
`defaultValue`	ComboboxValueType<Value, Multiple> \| null \| undefined ComboboxValueType<Value, Multiple> \| null \| undefined	`—`	The uncontrolled selected value of the combobox when it's initially rendered. To render a controlled combobox, use the `value` prop instead.
`actionsRef`	React.RefObject<AriaCombobox.Actions \| null> \| undefined React.RefObject<AriaCombobox.Actions \| null> \| undefined	`—`	A ref to imperative actions. - `unmount`: When specified, the combobox will not be unmounted when closed. Instead, the `unmount` function must be called to unmount the combobox manually. Useful when the combobox's animation is controlled by an external library.
`onOpenChange`	((open: boolean, eventDetails: ComboboxPrimitive.Root.ChangeEventDetails) => void) \| undef… ((open: boolean, eventDetails: ComboboxPrimitive.Root.ChangeEventDetails) => void) \| undefined	`—`	Event handler called when the popup is opened or closed.
`onInputValueChange`	((inputValue: string, eventDetails: ComboboxPrimitive.Root.ChangeEventDetails) => void) \| … ((inputValue: string, eventDetails: ComboboxPrimitive.Root.ChangeEventDetails) => void) \| undefined	`—`	Event handler called when the input value changes.
`onItemHighlighted`	((highlightedValue: Value \| undefined, eventDetails: ComboboxPrimitive.Root.HighlightEvent… ((highlightedValue: Value \| undefined, eventDetails: ComboboxPrimitive.Root.HighlightEventDetails) => void) \| undefined	`—`	Callback fired when an item is highlighted or unhighlighted. Receives the highlighted item value (or `undefined` if no item is highlighted) and event details with a `reason` property describing why the highlight changed. The `reason` can be: - `'keyboard'`: the highlight changed due to keyboard navigation. - `'pointer'`: the highlight changed due to pointer hovering. - `'none'`: the highlight changed programmatically.
`value`	ComboboxValueType<Value, Multiple> \| null \| undefined ComboboxValueType<Value, Multiple> \| null \| undefined	`—`	The selected value of the combobox. Use when controlled.
`onValueChange`	((value: ComboboxValueType<Value, Multiple> \| (Multiple extends true ? never : null), even… ((value: ComboboxValueType<Value, Multiple> \| (Multiple extends true ? never : null), eventDetails: ComboboxPrimitive.Root.ChangeEventDetails) => void) \| undefined	`—`	Event handler called when the selected value of the combobox changes.
