# Select

> Choose one or more values from a popup list of options.

Use `Select` for a form value chosen from a list. Use [Menu](/ui/components/surfaces/menu) for commands and actions.

## Single selection

```tsx theme={null}
import { Select } from 'twenty-ui/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.Trigger>
    <Select.Popup>
      {PRIORITIES.map(({ value, label }) => (
        <Select.Item key={value} value={value}>
          {label}
        </Select.Item>
      ))}
    </Select.Popup>
  </Select.Root>
);
```

Supply `items` on `Root` so `Value` renders the selected item's label; without it, the trigger shows the raw value. `defaultValue` initializes uncontrolled state; use `value` and `onValueChange` for controlled state. The selected value can be `null` when nothing is selected.

## Multiple selection

```tsx theme={null}
import { useState } from 'react';
import { Select } from 'twenty-ui/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.Trigger>
      <Select.Popup>
        {LANGUAGES.map(({ value, label }) => (
          <Select.Item key={value} value={value}>
            {label}
          </Select.Item>
        ))}
      </Select.Popup>
    </Select.Root>
  );
};
```

With `multiple`, the value is an array. The generic root types represent the option value and whether multiple selection is enabled.

## Parts and placement

| Part                  | Purpose                                                    |
| --------------------- | ---------------------------------------------------------- |
| `Root`                | Owns selection, open state, and form integration.          |
| `Trigger`             | Opens the list and supports `sm` or `md` sizing.           |
| `Value`               | Displays the selected label or a placeholder.              |
| `Popup`               | Provides the portal and positioned list.                   |
| `Item`                | Represents an option, with optional icons and description. |
| `Group`, `GroupLabel` | Group related options under an accessible label.           |
| `Separator`           | Separates groups visually.                                 |

`Popup` defaults to `side="bottom"`, `align="start"`, and `sideOffset={8}`. Set `alignItemWithTrigger` to align the selected option over the trigger. It uses the [theme's portal container](/ui/theming#scope-an-override) unless you provide `container`.

Keyboard users can open the list from the trigger, navigate options with arrow keys, and type to find an option. Escape dismisses the popup. Label the trigger or integrate the select with [Field](/ui/components/input/field); a placeholder alone does not name the control.

## Props

The reference is generated from the public component types. Native attributes, including accessible names and event handlers, are also accepted on parts that render elements.

### Select.Root

<ParamField body="Root.actionsRef" type="RefObject<SelectRootActions | null>">
  A ref to imperative actions.

  * `unmount`: Manually unmounts the select.
    Call this after any externally controlled closing animation finishes.
</ParamField>

<ParamField body="Root.autoComplete" type="string">
  Provides a hint to the browser for autofill.
</ParamField>

<ParamField body="Root.defaultOpen" type="boolean" default="false">
  Whether the select popup is initially open.

  To render a controlled select popup, use the `open` prop instead.
</ParamField>

<ParamField body="Root.defaultValue" type="SelectValueType<Value, Multiple> | null">
  The uncontrolled value of the select when it's initially rendered.

  To render a controlled select, use the `value` prop instead.
</ParamField>

<ParamField body="Root.disabled" type="boolean" default="false">
  Whether the component should ignore user interaction.
</ParamField>

<ParamField body="Root.form" type="string">
  Identifies the form that owns the hidden input.
  Useful when the select is rendered outside the form.
</ParamField>

<ParamField body="Root.highlightItemOnHover" type="boolean" default="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.
</ParamField>

<ParamField body="Root.id" type="string">
  The id of the Select.
</ParamField>

<ParamField body="Root.inputRef" type="Ref<HTMLInputElement>">
  A ref to access the hidden input element.
</ParamField>

<ParamField body="Root.isItemEqualToValue" type="((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.
</ParamField>

<ParamField body="Root.items" type="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.
</ParamField>

<ParamField body="Root.itemToStringLabel" type="((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.
</ParamField>

<ParamField body="Root.itemToStringValue" type="((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.

</ParamField>

<ParamField body="Root.modal" type="boolean" default="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.
</ParamField>

<ParamField body="Root.multiple" type="boolean" default="false">
  Whether multiple items can be selected.
</ParamField>

<ParamField body="Root.name" type="string">
  Identifies the field when a form is submitted.
