API reference

Derived from the installed component types. Native DOM props are also supported where applicable. A dash means no explicit default is documented. Some props depend on the selected mode.

Select

Select properties
Prop	Type	Default	Description
`children`	React.ReactNode React.ReactNode	`—`	Content rendered inside this component.
`inputRef`	React.Ref<HTMLInputElement> \| undefined React.Ref<HTMLInputElement> \| undefined	`—`	A ref to access the hidden input element.
`name`	string \| undefined string \| undefined	`—`	Identifies the field when a form is submitted.
`form`	string \| undefined string \| undefined	`—`	Identifies the form that owns the hidden input. Useful when the select is rendered outside the form.
`autoComplete`	string \| undefined string \| undefined	`—`	Provides a hint to the browser for autofill.
`id`	string \| undefined string \| undefined	`—`	The id of the Select.
`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 select popup.
`disabled`	boolean \| undefined boolean \| undefined	`false`	Whether the component should ignore user interaction.
`multiple`	Multiple \| undefined Multiple \| undefined	`false`	Whether multiple items can be selected.
`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.
`defaultOpen`	boolean \| undefined boolean \| undefined	`false`	Whether the select popup is initially open. To render a controlled select popup, use the `open` prop instead.
`onOpenChange`	((open: boolean, eventDetails: SelectRootChangeEventDetails) => void) \| undefined ((open: boolean, eventDetails: SelectRootChangeEventDetails) => void) \| undefined	`—`	Event handler called when the select popup is opened or closed.
`onOpenChangeComplete`	((open: boolean) => void) \| undefined ((open: boolean) => void) \| undefined	`—`	Event handler called after any animations complete when the select popup is opened or closed.
`open`	boolean \| undefined boolean \| undefined	`—`	Whether the select popup is currently open.
`modal`	boolean \| undefined boolean \| undefined	`true`	Determines if the select enters a modal state when open. - `true`: user interaction is limited to the select: document page scroll is locked and pointer interactions on outside elements are disabled. - `false`: user interaction with the rest of the document is allowed.
`actionsRef`	React.RefObject<SelectRootActions \| null> \| undefined React.RefObject<SelectRootActions \| null> \| undefined	`—`	A ref to imperative actions. - `unmount`: When specified, the select will not be unmounted when closed. Instead, the `unmount` function must be called to unmount the select manually. Useful when the select's animation is controlled by an external library.
`items`	readonly Group<any>[] \| Record<string, React.ReactNode> \| readonly { label: React.ReactNod… readonly Group<any>[] \| Record<string, React.ReactNode> \| readonly { label: React.ReactNode; value: any; }[] \| undefined	`—`	Data structure of the items rendered in the select popup. When specified, `<Select.Value>` renders the label of the selected item instead of the raw value.
`itemToStringLabel`	((itemValue: Value) => string) \| undefined ((itemValue: Value) => string) \| undefined	`—`	When the item values are objects (`<Select.Item value={object}>`), this function converts the object value to a string representation for display in the trigger. 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 (`<Select.Item value={object}>`), this function converts the object value to a string representation for form submission. If the shape of the object is `{ value, label }`, the value will be used automatically without needing to specify this prop.
`isItemEqualToValue`	((itemValue: Value, value: Value) => boolean) \| undefined ((itemValue: Value, value: Value) => boolean) \| undefined	`—`	Custom comparison logic used to determine if a select item value matches the current selected value. Useful when item values are objects without matching referentially. Defaults to `Object.is` comparison.
`defaultValue`	SelectValueType<Value, Multiple> \| null \| undefined SelectValueType<Value, Multiple> \| null \| undefined	`—`	The uncontrolled value of the select when it's initially rendered. To render a controlled select, use the `value` prop instead.
`value`	SelectValueType<Value, Multiple> \| null \| undefined SelectValueType<Value, Multiple> \| null \| undefined	`—`	The value of the select. Use when controlled.
`onValueChange`	((value: SelectValueType<Value, Multiple> \| (Multiple extends true ? never : null), eventD… ((value: SelectValueType<Value, Multiple> \| (Multiple extends true ? never : null), eventDetails: SelectRootChangeEventDetails) => void) \| undefined	`—`	Event handler called when the value of the select changes.

`render`	React.ReactElement<unknown, string \| React.JSXElementConstructor<any>> \| ComponentRenderFn… React.ReactElement<unknown, string \| React.JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, SelectPopupState> \| undefined	`—`	Allows you to replace the component's HTML element with a different tag, or compose it with another component.
