Seleccionar

Resumen

Use Select para un valor de formulario elegido de una lista. Dropdown sigue siendo la API principal de nivel superior para menús, selectores, paneles y páginas que combinan esos Workflows.

”Uso”

Estado no controlado.

Usa defaultValue para establecer la prioridad inicial. El selector gestiona los cambios de selección posteriores.

import { Select } from 'twenty-ui/primitives/input';

const PRIORITIES = [
  { value: 'low', label: 'Low' },
  { value: 'normal', label: 'Normal' },
  { value: 'high', label: 'High' },
];

export const PrioritySelect = () => (
  <Select.Root name="priority" defaultValue="normal" items={PRIORITIES}>
    <Select.Trigger aria-label="Priority">
      <Select.Value placeholder="Choose a priority" />
      <Select.Icon />
    </Select.Trigger>
    <Select.Portal>
      <Select.Positioner
        align="start"
        sideOffset={8}
        alignItemWithTrigger={false}
      >
        <Select.Popup>
          {PRIORITIES.map(({ value, label }) => (
            <Select.Item key={value} value={value}>
              <Select.ItemText>{label}</Select.ItemText>
              <Select.ItemIndicator />
            </Select.Item>
          ))}
        </Select.Popup>
      </Select.Positioner>
    </Select.Portal>
  </Select.Root>
);

Proporcione items en Root para que Value muestre la etiqueta del elemento seleccionado; sin ellos, el activador muestra el valor sin procesar. El valor seleccionado puede ser null cuando no hay nada seleccionado.

Anatomía

Compón las partes públicas dentro de Select.Root. Trigger e Item procesan únicamente sus elementos secundarios. Añade Icon, ItemText e ItemIndicator explícitamente cuando quieras el chevrón, la etiqueta y la marca de verificación predeterminados.

Parte	Propósito
`Root`	Gestiona la selección, el estado abierto, los valores genéricos y la integración con formularios nativos.
`Label`	Asocia una etiqueta visible con el disparador.
`Disparador`	Abre la lista y contiene el valor mostrado.
`Valor`	Representa la etiqueta seleccionada o un marcador de posición.
`Icon`	Representa un galón predeterminado o elementos secundarios personalizados en el disparador.
`Portal`	Mueve el contenido emergente al contenedor del portal del tema o a un contenedor explícito.
`Backdrop`	Proporciona un fondo opcional mientras la ventana emergente está abierta.
`Positioner`	Gestiona la geometría del ancla, la ubicación, los desplazamientos y el comportamiento ante colisiones.
`Popup`	Representa la superficie emergente sin añadir un portal ni un posicionador.
`Lista`	Proporciona un contenedor de desplazamiento independiente para las opciones.
`Item`	Proporciona comportamiento de selección para una opción.
`ItemText`	Identifica la etiqueta de opción utilizada para la búsqueda anticipada y la alineación del valor seleccionado.
`ItemIndicator`	Representa la marca de verificación predeterminada de la opción seleccionada o elementos secundarios personalizados.
`Arrow`	Coloca una flecha opcional junto al ancla de la ventana emergente.
`ScrollUpArrow`, `ScrollDownArrow`	Desplaza una lista larga al pasar el cursor.
`Group`, `GroupLabel`	Agrupa las opciones relacionadas bajo una etiqueta.
`Separator`	Separa los grupos visualmente.

Portal, List, Backdrop, las flechas y los indicadores son opcionales. Usa Positioner alrededor de Popup para el posicionamiento, incluso cuando representes la ventana emergente en línea sin un portal.

Estado controlado

Pasa value y actualízalo con onValueChange para gestionar la misma prioridad en el estado de React. La devolución de llamada recibe el siguiente valor y los detalles del evento.

import { useState } from 'react';
import { Select } from 'twenty-ui/primitives/input';

const PRIORITIES = [
  { value: 'low', label: 'Low' },
  { value: 'normal', label: 'Normal' },
  { value: 'high', label: 'High' },
];

export const PrioritySelect = () => {
  const [priority, setPriority] = useState<string | null>('normal');

  return (
    <Select.Root
      name="priority"
      value={priority}
      onValueChange={setPriority}
      items={PRIORITIES}
    >
      <Select.Trigger aria-label="Priority">
        <Select.Value placeholder="Choose a priority" />
        <Select.Icon />
      </Select.Trigger>
      <Select.Portal>
        <Select.Positioner
          align="start"
          sideOffset={8}
          alignItemWithTrigger={false}
        >
          <Select.Popup>
            {PRIORITIES.map(({ value, label }) => (
              <Select.Item key={value} value={value}>
                <Select.ItemText>{label}</Select.ItemText>
                <Select.ItemIndicator />
              </Select.Item>
            ))}
          </Select.Popup>
        </Select.Positioner>
      </Select.Portal>
    </Select.Root>
  );
};

Selección múltiple

import { useState } from 'react';
import { Select } from 'twenty-ui/primitives/input';

const LANGUAGES = [
  { value: 'en', label: 'English' },
  { value: 'fr', label: 'French' },
  { value: 'es', label: 'Spanish' },
];

export const LanguageSelect = () => {
  const [languages, setLanguages] = useState<string[]>(['en']);

  return (
    <Select.Root
      multiple
      value={languages}
      onValueChange={setLanguages}
      items={LANGUAGES}
    >
      <Select.Trigger aria-label="Languages">
        <Select.Value placeholder="Choose languages" />
        <Select.Icon />
      </Select.Trigger>
      <Select.Portal>
        <Select.Positioner
          align="start"
          sideOffset={8}
          alignItemWithTrigger={false}
        >
          <Select.Popup>
            {LANGUAGES.map(({ value, label }) => (
              <Select.Item key={value} value={value}>
                <Select.ItemText>{label}</Select.ItemText>
                <Select.ItemIndicator />
              </Select.Item>
            ))}
          </Select.Popup>
        </Select.Positioner>
      </Select.Portal>
    </Select.Root>
  );
};

Con multiple, el valor es una matriz. Usa defaultValue={['en']} en lugar de value y onValueChange para una selección múltiple no controlada. Los tipos genéricos de raíz representan el valor de la opción y si la selección múltiple está habilitada.

Estado abierto

La selección y la visibilidad de la ventana emergente son independientes. Los ejemplos anteriores dejan la visibilidad de la ventana emergente sin controlar. Seleccionar un único valor cierra la ventana emergente; la selección múltiple la mantiene abierta. Usa defaultOpen para establecer su visibilidad inicial; su valor predeterminado es false. Pasa open y actualízalo con onOpenChange para controlar la visibilidad. Este ejemplo controla la ventana emergente y deja la prioridad seleccionada sin controlar.

import { useState } from 'react';
import { Select } from 'twenty-ui/primitives/input';

const PRIORITIES = [
  { value: 'low', label: 'Low' },
  { value: 'normal', label: 'Normal' },
  { value: 'high', label: 'High' },
];

export const PrioritySelect = () => {
  const [open, setOpen] = useState(false);

  return (
    <Select.Root
      name="priority"
      defaultValue="normal"
      items={PRIORITIES}
      open={open}
      onOpenChange={setOpen}
    >
      <Select.Trigger aria-label="Priority">
        <Select.Value placeholder="Choose a priority" />
        <Select.Icon />
      </Select.Trigger>
      <Select.Portal>
        <Select.Positioner
          align="start"
          sideOffset={8}
          alignItemWithTrigger={false}
        >
          <Select.Popup>
            {PRIORITIES.map(({ value, label }) => (
              <Select.Item key={value} value={value}>
                <Select.ItemText>{label}</Select.ItemText>
                <Select.ItemIndicator />
              </Select.Item>
            ))}
          </Select.Popup>
        </Select.Positioner>
      </Select.Portal>
    </Select.Root>
  );
};

Combinar con un campo

Envuelve el selector en Field.Root para asociar su activador con una etiqueta visible y texto de ayuda. El campo gestiona el etiquetado y la validación; el selector mantiene su propio estado de selección y ventana emergente.

import { Field, Select } from 'twenty-ui/primitives/input';

const PRIORITIES = [
  { value: 'low', label: 'Low' },
  { value: 'normal', label: 'Normal' },
  { value: 'high', label: 'High' },
];

export const PriorityField = () => (
  <Field.Root name="priority">
    <Field.Label>Priority</Field.Label>
    <Select.Root name="priority" defaultValue="normal" items={PRIORITIES}>
      <Select.Trigger>
        <Select.Value />
        <Select.Icon />
      </Select.Trigger>
      <Select.Portal>
        <Select.Positioner
          align="start"
          sideOffset={8}
          alignItemWithTrigger={false}
        >
          <Select.Popup>
            {PRIORITIES.map(({ value, label }) => (
              <Select.Item key={value} value={value}>
                <Select.ItemText>{label}</Select.ItemText>
                <Select.ItemIndicator />
              </Select.Item>
            ))}
          </Select.Popup>
        </Select.Positioner>
      </Select.Portal>
    </Select.Root>
    <Field.Description>
      Choose how soon this record needs attention.
    </Field.Description>
  </Field.Root>
);

Composición de elementos

Compón contenido arbitrario dentro de Item. Coloca la etiqueta buscable en ItemText; el contenido adicional no se convierte en su etiqueta de búsqueda anticipada. Proporciona elementos secundarios a Icon o ItemIndicator para reemplazar sus iconos predeterminados, u omite esas partes por completo.

import { Select } from 'twenty-ui/primitives/input';

export const PrioritySelect = () => (
  <Select.Root defaultValue="high" items={{ high: 'High' }}>
    <Select.Trigger aria-label="Priority">
      <Select.Value />
      <Select.Icon />
    </Select.Trigger>
    <Select.Portal>
      <Select.Positioner
        align="start"
        sideOffset={8}
        alignItemWithTrigger={false}
      >
        <Select.Popup>
          <Select.Item value="high">
            <Select.ItemText>High</Select.ItemText>
            <span>Needs attention today</span>
            <Select.ItemIndicator />
          </Select.Item>
        </Select.Popup>
      </Select.Positioner>
    </Select.Portal>
  </Select.Root>
);

Todas las partes que representan elementos aceptan atributos nativos, referencias y las API de composición render, className y style de Base UI. Por ejemplo, usa render={<Button />} en Trigger para componerlo con un botón de Twenty UI. Para un elemento de representación que no sea un botón, establece también nativeButton={false}.

Ubicación

Establece size="sm" o size="md" en Trigger. La ubicación pertenece a Positioner; el destino del portal pertenece a Portal. Positioner conserva los valores predeterminados de Base UI: side="bottom", align="center", sideOffset={0} y alignItemWithTrigger={true}. La alineación del elemento seleccionado se aplica a la entrada mediante puntero cuando hay suficiente espacio. Establece alignItemWithTrigger={false} para usar un posicionamiento anclado de forma coherente. Los ejemplos anteriores eligen explícitamente align="start" y sideOffset={8}.

import { useRef, useState } from 'react';
import { Button, Select } from 'twenty-ui/primitives/input';

const PRIORITIES = [
  { value: 'low', label: 'Low' },
  { value: 'normal', label: 'Normal' },
  { value: 'high', label: 'High' },
];

export const PositionedPrioritySelect = () => {
  const anchorRef = useRef<HTMLButtonElement>(null);
  const boundaryRef = useRef<HTMLDivElement>(null);
  const [portalContainer, setPortalContainer] = useState<HTMLDivElement | null>(
    null,
  );

  return (
    <div ref={boundaryRef}>
      <Button ref={anchorRef}>Position anchor</Button>
      <Select.Root defaultValue="normal" items={PRIORITIES}>
        <Select.Trigger aria-label="Priority">
          <Select.Value />
          <Select.Icon />
        </Select.Trigger>
        <Select.Portal container={portalContainer}>
          <Select.Positioner
            anchor={anchorRef}
            positionMethod="fixed"
            side="inline-end"
            align="start"
            alignItemWithTrigger={false}
            sideOffset={({ anchor }) => anchor.width / 4}
            alignOffset={4}
            collisionBoundary={boundaryRef.current ?? undefined}
            collisionPadding={12}
            collisionAvoidance={{ side: 'flip', align: 'shift' }}
            sticky
          >
            <Select.Popup>
              <Select.Arrow />
              <Select.List>
                {PRIORITIES.map(({ value, label }) => (
                  <Select.Item key={value} value={value}>
                    <Select.ItemText>{label}</Select.ItemText>
                    <Select.ItemIndicator />
                  </Select.Item>
                ))}
              </Select.List>
            </Select.Popup>
          </Select.Positioner>
        </Select.Portal>
      </Select.Root>
      <div ref={setPortalContainer} />
    </div>
  );
};

Positioner también admite anclas virtuales, funciones de desplazamiento, arrowPadding y disableAnchorTracking. Portal usa el contenedor del portal del tema, a menos que proporciones container. Un container={null} explícito espera hasta que ese contenedor esté disponible.

Formularios nativos y detalles de las devoluciones de llamada

Establece name en Root para incluir el valor seleccionado en FormData. La selección múltiple envía una entrada por cada valor seleccionado. form asocia la entrada oculta con un formulario externo, y inputRef proporciona acceso a esa entrada. required, disabled y autoComplete conservan el comportamiento de formulario nativo de Base UI. onValueChange y onOpenChange reciben el siguiente estado y los detalles del evento ascendente, incluidos reason, el event nativo, cancel() y allowPropagation(). Llamar a cancel() impide el cambio de estado interno correspondiente. Las raíces controladas aún requieren que actualices value u open.

import { useState } from 'react';
import { Select } from 'twenty-ui/primitives/input';

const PRIORITIES = [
  { value: 'normal', label: 'Normal' },
  { value: 'high', label: 'High' },
];

type PrioritySelectProps = { canSetHighPriority: boolean };

export const PrioritySelect = ({ canSetHighPriority }: PrioritySelectProps) => {
  const [priority, setPriority] = useState<string | null>('normal');

  return (
    <Select.Root
      items={PRIORITIES}
      value={priority}
      onValueChange={(nextPriority, details) => {
        if (nextPriority === 'high' && !canSetHighPriority) {
          details.cancel();
          return;
        }
        setPriority(nextPriority);
      }}
    >
      <Select.Trigger aria-label="Priority">
        <Select.Value />
        <Select.Icon />
      </Select.Trigger>
      <Select.Portal>
        <Select.Positioner
          align="start"
          sideOffset={8}
          alignItemWithTrigger={false}
        >
          <Select.Popup>
            {PRIORITIES.map(({ value, label }) => (
              <Select.Item key={value} value={value}>
                <Select.ItemText>{label}</Select.ItemText>
                <Select.ItemIndicator />
              </Select.Item>
            ))}
          </Select.Popup>
        </Select.Positioner>
      </Select.Portal>
    </Select.Root>
  );
};

Los tipos genéricos de raíz representan el valor de la opción y si la selección múltiple está habilitada. Los valores de objeto admiten itemToStringLabel, itemToStringValue e isItemEqualToValue. Usa null para una selección única vacía y un arreglo vacío para una selección múltiple vacía.

Teclado

Los usuarios de teclado pueden abrir la lista desde el activador, navegar por las opciones con las teclas de flecha y escribir para encontrar una opción. Inicio y Fin saltan a la primera y la última opción. Intro selecciona una opción; Escape descarta la ventana emergente y restaura el foco del disparador. La selección múltiple mantiene abierta la ventana emergente mientras se alternan las opciones. Etiqueta el disparador con Select.Label, un nombre accesible o Field. Un marcador de posición por sí solo no da nombre al control.

”Props”

La referencia se genera a partir de los tipos de componentes públicos. Los atributos nativos, incluidos los nombres accesibles y los controladores de eventos, también se aceptan en las partes que representan elementos.

Select.Root

RefObject<SelectRootActions | null>

A ref to imperative actions.

unmount: Ends the closing phase of the select after an externally controlled closing animation finishes. Call preventUnmountOnClose() in onOpenChange first, otherwise the select completes closing on its own. Whether it leaves the DOM is decided by keepMounted on the portal.
close: Closes the select imperatively when called.

string

Provides a hint to the browser for autofill.

ReactNode

Select parts sharing selection, open state and accessible relationships. Root renders no DOM node.

boolean

predeterminado:"false"

Whether the select popup is initially open.To render a controlled select popup, use the open prop instead.

SelectInputValue<Value, Multiple> | null

The uncontrolled value of the select when it’s initially rendered.To render a controlled select, use the value prop instead.

boolean

predeterminado:"false"

Whether the component should ignore user interaction.

string

Identifies the form that owns the hidden input. Useful when the select is rendered outside the form.

boolean

predeterminado:"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.

string

The id of the Select.

Ref<HTMLInputElement>

Ref to the native hidden input used for form submission.

((itemValue: Value, value: Value) => boolean)

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.

Record<string, ReactNode> | readonly { label: ReactNode; value: any; }[] | readonly Group<any>[]

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.

((itemValue: Value) => string)

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.

((itemValue: Value) => string)

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.

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.

boolean

predeterminado:"false"

Whether multiple items can be selected.

string

Identifies the field when a form is submitted.

((open: boolean, eventDetails: SelectRootOpenChangeEventDetails) => void)

Receives the requested open state and unchanged Base UI event details.

((open: boolean) => void)

Event handler called after any animations complete when the select popup is opened or closed.

((value: SelectOutputValue<Value, Multiple> | (Multiple extends true ? never : null), eventDetails: SelectRootChangeEventDetails) => void)

Receives the requested generic value and unchanged Base UI event details, including reason, event and cancel(). Multiple selection receives an array; a cleared single value is null.

boolean

Whether the select popup is currently open.

boolean

predeterminado:"false"

Whether the user should be unable to choose a different option from the select popup.

boolean

predeterminado:"false"

Whether the user must choose a value before submitting a form.

SelectInputValue<Value, Multiple> | null

The value of the select. Use when controlled.

Select.Label

string | ((state: FieldRootState) => string | undefined)

CSS class applied to the element, or a function that returns a class based on the component’s state.

ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, FieldRootState>

Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.

CSSProperties | ((state: FieldRootState) => CSSProperties | undefined)

Style applied to the element, or a function that returns a style object based on the component’s state.

Select.Trigger

ReactNode

Trigger content rendered as supplied. Compose Value and Icon explicitly.

string | ((state: SelectTriggerState) => string | undefined)

CSS class applied to the element, or a function that returns a class based on the component’s state.

boolean

Whether the component should ignore user interaction.

boolean

predeterminado:"true"

Whether the component renders a native <button> element when replacing it via the render prop. Set to false if the rendered element is not a button (for example, <div>).

Ref<HTMLButtonElement>

Ref to the rendered trigger element, a button by default.

ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, SelectTriggerState>

Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.

"md" | "sm"

predeterminado:"md"

Visual size of the trigger. Defaults to md.

CSSProperties | ((state: SelectTriggerState) => CSSProperties | undefined)

Style applied to the element, or a function that returns a style object based on the component’s state.

Select.Value

ReactNode | ((value: any) => ReactNode)

Accepts a function that returns a ReactNode to format the selected value. Treat the value as read-only: in multiple mode it may be a shared frozen array when nothing is selected.

string | ((state: SelectValueState) => string | undefined)

CSS class applied to the element, or a function that returns a class based on the component’s state.

ReactNode

The placeholder value to display when no value is selected. This is overridden by children if specified, or by a null item’s label in items.

ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, SelectValueState>

Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.

CSSProperties | ((state: SelectValueState) => CSSProperties | undefined)

Style applied to the element, or a function that returns a style object based on the component’s state.

Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.

CSSProperties | ((state: SelectIconState) => CSSProperties | undefined)

Style applied to the element, or a function that returns a style object based on the component’s state.

Select.Portal

string | ((state: SelectPortalState) => string | undefined)

CSS class applied to the element, or a function that returns a class based on the component’s state.

Portal destination. Defaults to the current theme container, then the document body. Explicit null waits for a container before mounting.

Ref<HTMLDivElement>

Ref to the portal div. Native props and render apply to this element.

ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, SelectPortalState>

Select.Positioner

"center" | "end" | "start"

predeterminado:"center"

How to align the popup relative to the specified side.

boolean

predeterminado:"true"

Uses the upstream selected-item alignment by default. Set false to use side, align and offsets without overlapping the trigger.

number | OffsetFunction

predeterminado:"0"

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.

An element to position the popup against. By default, the popup will be positioned against the trigger.

number

CollisionAvoidance

Determines how to handle collisions when positioning the popup.side controls overflow on the preferred placement axis (top/bottom or left/right):

'flip': keep the requested side when it fits; otherwise try the opposite side (top and bottom, or left and right).
'shift': never change side; keep the requested side and move the popup within the clipping boundary so it stays visible.
'none': do not correct side-axis overflow.

align controls overflow on the alignment axis (start/center/end):

'flip': keep side, but swap start and end when the requested alignment overflows.
'shift': keep side and requested alignment, then nudge the popup along the alignment axis to fit.
'none': do not correct alignment-axis overflow.

fallbackAxisSide controls fallback behavior on the perpendicular axis when the preferred axis cannot fit:

'start': allow perpendicular fallback and try the logical start side first (top before bottom, or left before right in LTR).
'end': allow perpendicular fallback and try the logical end side first (bottom before top, or right before left in LTR).
'none': do not fallback to the perpendicular axis.

When side is 'shift', explicitly setting align only supports 'shift' or 'none'. If align is omitted, it defaults to 'flip'.

Boundary

predeterminado:"clipping-ancestors"

An element or a rectangle that delimits the area that the popup is confined to.

Padding
