SelectField

String-valued convenience control; compound Select remains available for richer collections.

Dependency-resolved declaration properties. Common React/native HTML attributes are omitted from the table; use the full declaration and React/native references. Generic and union restrictions remain authoritative in TypeScript.

Select

Public component; use the linked family guide for complete composition and behavior.

Select.Root

Property	Required	Type	Meaning
`actionsRef`	No	`React.RefObject<SelectRootActions \| null> \| undefined`	A ref to imperative actions. - `unmount`: Manually unmounts the select. Call this after any externally controlled closing animation finishes.
`autoComplete`	No	`string \| undefined`	Provides a hint to the browser for autofill.
`children`	No	`React.ReactNode`	See the usage contract and declaration.
`defaultOpen`	No	`boolean \| undefined`	Whether the select popup is initially open. To render a controlled select popup, use the `open` prop instead.
`defaultValue`	No	`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.
`disabled`	No	`boolean \| undefined`	Whether the component should ignore user interaction.
`form`	No	`string \| undefined`	Identifies the form that owns the hidden input. Useful when the select is rendered outside the form.
`highlightItemOnHover`	No	`boolean \| undefined`	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`	No	`string \| undefined`	The id of the Select.
`inputRef`	No	`React.Ref<HTMLInputElement> \| undefined`	A ref to access the hidden input element.
`isItemEqualToValue`	No	`((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.
`items`	No	`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`	No	`((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`	No	`((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.
`modal`	No	`boolean \| undefined`	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`	No	`Multiple \| undefined`	Whether multiple items can be selected.
`name`	No	`string \| undefined`	Identifies the field when a form is submitted.
`onOpenChange`	No	`((open: boolean, eventDetails: SelectRootChangeEventDetails) => void) \| undefined`	Event handler called when the select popup is opened or closed.
`onOpenChangeComplete`	No	`((open: boolean) => void) \| undefined`	Event handler called after any animations complete when the select popup is opened or closed.

`alignOffset`	No	`number \| OffsetFunction \| undefined`	Additional offset along the alignment axis in pixels. Also accepts a function that returns the offset to read the dimensions of the anchor and positioner elements, along with its side and alignment. The function takes a `data` object parameter with the following properties: - `data.anchor`: the dimensions of the anchor element with properties `width` and `height`. - `data.positioner`: the dimensions of the positioner element with properties `width` and `height`. - `data.side`: which side of the anchor element the positioner is aligned against. - `data.align`: how the positioner is aligned relative to the specified side.

`sideOffset`	No	`number \| OffsetFunction \| undefined`	Distance between the anchor and the popup in pixels.

The function takes a `data` object parameter with the following properties: - `data.anchor`: the dimensions of the anchor element with properties `width` and `height`. - `data.positioner`: the dimensions of the positioner element with properties `width` and `height`. - `data.side`: which side of the anchor element the positioner is aligned against. - `data.align`: how the positioner is aligned relative to the specified side.

Defaults and customization

Descriptor defaults: {"size":"md","tone":"neutral","variant":"outline"}. Parts: trigger, value, icon, positioner, popup, item, item-text, item-indicator, group, group-label, scroll-up-arrow, scroll-down-arrow. Explicit instance props take precedence over configured defaults.

Use semantic tokens, public part hooks and customization sheets. Keep visual configuration separate from application state.

State, events and accessibility

For interactive controls, pair a controlled value/open prop with its corresponding change callback; default props initialize uncontrolled state. Keep application validation and submission policy explicit. Name controls with visible labels, name icon-only actions on the button, and preserve focus and dismissal behavior when replacing parts. Use native form names and submit/reset types where supported. See the usage guide for component-specific behavior and live examples.

Declaration authority

Generated from packages/faye-ui/dist/controls/select.d.ts after the semantic package build. Common native/React attributes are intentionally omitted from property tables. Generic overloads, discriminated unions and complete inherited attributes remain authoritative in installed TypeScript declarations. React DOM attributes and Base UI component contracts describe the inherited foundations.
