Props

Select

Props de Select
Prop	Type	Default	Description
actionsRef	`React.RefObject<SelectRootActions \| null>`	sem valor padrão	A ref to imperative actions. - `unmount`: Manually unmounts the select. Call this after any externally controlled closing animation finishes.
autoComplete	`string`	sem valor padrão	Provides a hint to the browser for autofill.
children	`React.ReactNode`	sem valor padrão
defaultOpen	`boolean`	`false`	Whether the select popup is initially open. To render a controlled select popup, use the `open` prop instead.
defaultValue	`SelectValueType<Value, Multiple> \| null`	sem valor padrão	The uncontrolled value of the select when it's initially rendered. To render a controlled select, use the `value` prop instead.
disabled	`boolean`	`false`	Whether the component should ignore user interaction.
form	`string`	sem valor padrão	Identifies the form that owns the hidden input. Useful when the select is rendered outside the form.
highlightItemOnHover	`boolean`	`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.
id	`string`	sem valor padrão	The id of the Select.
inputRef	`React.Ref<HTMLInputElement>`	sem valor padrão	A ref to access the hidden input element.
isItemEqualToValue	`((itemValue: Value, value: Value) => boolean)`	sem valor padrão	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.
items	`readonly Group<any>[] \| Record<string, React.ReactNode> \| readonly { label: React.ReactNode; value: any; }[]`	sem valor padrão	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)`	sem valor padrão	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)`	sem valor padrão	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.
modal	`boolean`	`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. On touch devices, a `true` modal blocks outside taps but leaves the page scrollable unless the popup spans nearly the full viewport width, matching native iOS behavior.
multiple	`Multiple`	`false`	Whether multiple items can be selected.
name	`string`	sem valor padrão	Identifies the field when a form is submitted.
onOpenChange	`((open: boolean, eventDetails: SelectRootChangeEventDetails) => void)`	sem valor padrão	Event handler called when the select popup is opened or closed.
onOpenChangeComplete	`((open: boolean) => void)`	sem valor padrão	Event handler called after any animations complete when the select popup is opened or closed.
onValueChange	`((value: SelectValueType<Value, Multiple> \| (Multiple extends true ? never : null), eventDetails: SelectRootChangeEventDetails) => void)`	sem valor padrão	Event handler called when the value of the select changes.
open	`boolean`	sem valor padrão	Whether the select popup is currently open.
readOnly	`boolean`	`false`	Whether the user should be unable to choose a different option from the select popup.
required	`boolean`	`false`	Whether the user must choose a value before submitting a form.
value	`SelectValueType<Value, Multiple> \| null`	sem valor padrão	The value of the select. Use when controlled.

Estende SelectRoot.Props<Value, Multiple>.

Notas de acessibilidade

Teclado verificado por teste: ArrowDown abre e percorre a lista, ArrowUp volta, Enter escolhe o item destacado, Escape desiste sem alterar o valor, e o foco retorna ao trigger nos dois desfechos. Um select desabilitado sai da ordem de tabulação, e um item desabilitado continua anunciado sem poder ser escolhido. Leitor de tela verificado em navegador: o trigger é um combobox nomeado pelo rótulo do campo, aria-expanded acompanha o estado, o popup portalizado é ligado por aria-controls e expõe options com a seleção atual marcada; a escolha é reportada pelo rótulo do item, não pelo valor bruto, e aria-invalid é exposto sem trocar o papel do controle. Touch verificado em viewport de 375px com emulação de toque: o trigger e cada opção medem acima do mínimo de 24x24 da WCAG 2.2 SC 2.5.8, e abrir e escolher funcionam por toque. Reduced motion verificado com prefers-reduced-motion: reduce — os tokens de motion colapsam para 1ms e a animação de entrada do popup mede 0.001s, sem perder a abertura nem a escolha.
