Usage guidelines

  • Prefer Combobox for large lists: Select is not filterable, aside from basic keyboard typeahead functionality to find items by focusing and highlighting them. Prefer Combobox instead of Select when the number of items is sufficiently large to warrant filtering.
  • Special positioning behavior: The select popup by default overlaps its trigger so the selected item’s text is aligned with the trigger’s value text. This behavior can be disabled or customized.
  • Form controls must have an accessible name: Prefer <Select.Label>, or provide an aria-label on <Select.Trigger> when no visible label is rendered. See Labeling a select and the forms guide.
  • Closing animations: The popup stays rendered until its closing animation finishes. See JavaScript animations for animating it with Motion and for manual control.

Anatomy

Import the component and assemble its parts:

Anatomy
import { Select } from 'base-ui-solid/select';

<Select.Root>
  <Select.Label />
  <Select.Trigger>
    <Select.Value />
    <Select.Icon />
  </Select.Trigger>

  <Select.Portal>
    <Select.Backdrop />
    <Select.Positioner>
      <Select.Popup>
        <Select.ScrollUpArrow />
        <Select.Arrow />
        <Select.List>
          <Select.Item>
            <Select.ItemText />
            <Select.ItemIndicator />
          </Select.Item>
          <Select.Separator />
          <Select.Group>
            <Select.GroupLabel />
          </Select.Group>
        </Select.List>
        <Select.ScrollDownArrow />
      </Select.Popup>
    </Select.Positioner>
  </Select.Portal>
</Select.Root>;

Positioning

<Select.Positioner> has a special prop called alignItemWithTrigger which causes the positioning to act differently by default from other Positioner components. The prop makes the select popup overlap the trigger so the selected item’s text is aligned with the trigger’s value text.

For styling, data-side is "none" on the .Popup and .Positioner parts when the mode is active.

To prevent the select popup from overlapping its trigger, set the alignItemWithTrigger prop to false. When set to true (its default) there are a few important points to note about its behavior:

  • Interaction type dependent: For UX reasons, the alignItemWithTrigger positioning mode is disabled if touch was the pointer type used to open the popup.
  • Viewport space dependent: There must be enough space in the viewport to align the selected item’s text with the trigger’s value text without causing the popup to be too vertically small — otherwise, it falls back to the default positioning mode. This can be customized by setting min-height on the <Select.Positioner> element; a smaller value will fallback less often. Additionally, the trigger must be at least 20px from the edges of the top and bottom of the viewport, or it will also fall back.
  • Other positioning props are ignored: Props like side or align have no effect unless the prop is set to false or when in fallback mode.

Examples

Typed wrapper component

The following example shows a typed wrapper around the Select component with correct type inference and type safety:

Specifying generic type parameters
import type { JSX } from '@solidjs/web';
import { Select } from 'base-ui-solid/select';

export function MySelect<Value, Multiple extends boolean | undefined = false>(
  props: Select.Root.Props<Value, Multiple>,
): JSX.Element {
  return <Select.Root {...props}>{/* ... */}</Select.Root>;
}

Formatting the value

By default, the <Select.Value> component renders the raw value.

Passing the items prop to <Select.Root> instead renders the matching label for the rendered value:

items prop
const items = [
  { value: null, label: 'Select theme' },
  { value: 'system', label: 'System default' },
  { value: 'light', label: 'Light' },
  { value: 'dark', label: 'Dark' },
];

<Select.Root items={items}>
  <Select.Value />
</Select.Root>;

A function can also be passed as the children prop of <Select.Value> to render a formatted value:

Lookup map
const items = {
  monospace: 'Monospace',
  serif: 'Serif',
  'san-serif': 'Sans-serif',
};

<Select.Value>
  {(value: keyof typeof items) => (
    <span style={{ 'font-family': value }}>
      {items[value]}
    </span>
  )}
</Select.Value>;

To avoid lookup, object values for each item can also be used.

Labeling a select

Use <Select.Label> to provide a visible label for the select trigger:

Using Select.Label to label a select
<Select.Root>
  <Select.Label>Theme</Select.Label>
  {/* ... */}
</Select.Root>

<Select.Label> renders a <div>, so clicking it focuses the select trigger without opening the popup.

Placeholder values

To show a placeholder value, use the placeholder prop on <Select.Value>:

Placeholder item
const items = [
  { value: 'system', label: 'System default' },
  { value: 'light', label: 'Light' },
  { value: 'dark', label: 'Dark' },
];

<Select.Root items={items}>
  <Select.Value placeholder="Select theme" />
</Select.Root>;

With placeholders, users cannot clear selected values using the select itself. If the select value should be clearable from the popup (instead of an external “reset” button), use a null item rendered in the list itself:

Clearable item
const items = [
  { value: null, label: 'Select theme' },
  { value: 'system', label: 'System default' },
  { value: 'light', label: 'Light' },
  { value: 'dark', label: 'Dark' },
];

<Select.Root items={items}>
  <Select.Value />
</Select.Root>;

Multiple selection

Add the multiple prop to the <Select.Root> component to allow multiple selections.

Languages
import { For } from 'solid-js';
import type { JSX } from '@solidjs/web';
import { Select } from 'base-ui-solid/select';
import styles from './index.module.css';

const languages = {
  javascript: 'JavaScript',
  typescript: 'TypeScript',
  python: 'Python',
  java: 'Java',
  csharp: 'C#',
  php: 'PHP',
  cpp: 'C++',
  rust: 'Rust',
  go: 'Go',
  swift: 'Swift',
};

type Language = keyof typeof languages;

const values = Object.keys(languages) as Language[];

function renderValue(value: Language[]) {
  if (value.length === 0) {
    return 'Select languages';
  }

  const firstLanguage = languages[value[0]];
  const additionalLanguages = value.length > 1 ? ` (+${value.length - 1} more)` : '';
  return firstLanguage + additionalLanguages;
}

export default function MultiSelectExample() {
  return (
    <div class={styles.Field}>
      <Select.Root multiple defaultValue={['javascript', 'typescript']}>
        <Select.Label class={styles.Label}>Languages</Select.Label>
        <Select.Trigger class={styles.Select}>
          <Select.Value class={styles.Value}>{renderValue}</Select.Value>
          <Select.Icon>
            <CaretUpDownIcon />
          </Select.Icon>
        </Select.Trigger>
        <Select.Portal>
          <Select.Positioner class={styles.Positioner} sideOffset={4} alignItemWithTrigger={false}>
            <Select.Popup class={styles.Popup}>
              <For each={values}>
                {(value) => (
                  <Select.Item value={value} class={styles.Item}>
                    <Select.ItemIndicator class={styles.ItemIndicator}>
                      <CheckIcon />
                    </Select.ItemIndicator>
                    <Select.ItemText class={styles.ItemText}>{languages[value]}</Select.ItemText>
                  </Select.Item>
                )}
              </For>
            </Select.Popup>
          </Select.Positioner>
        </Select.Portal>
      </Select.Root>
    </div>
  );
}

function CaretUpDownIcon(
  props: Omit<JSX.IntrinsicElements['svg'], 'style'> & { style?: JSX.CSSProperties },
) {
  return (
    <svg
      width="16"
      height="16"
      viewBox="0 0 16 16"
      fill="currentColor"
      {...props}
      style={{ display: 'block', ...props.style }}
    >
      <path d="M11 10H5l3 3.5zm0-4H5l3-3.5z" />
    </svg>
  );
}

function CheckIcon(
  props: Omit<JSX.IntrinsicElements['svg'], 'style'> & { style?: JSX.CSSProperties },
) {
  return (
    <svg
      width="16"
      height="16"
      viewBox="0 0 16 16"
      fill="none"
      stroke="currentColor"
      {...props}

    >
      <path d="m2.5 8.5 4 4 7-9" />
    </svg>
  );
}

Object values

Select items can use objects as values instead of primitives. This lets you access the full object in custom render functions, and can avoid needing to specify items for lookup.

Shipping method
import { For } from 'solid-js';
import type { JSX } from '@solidjs/web';
import { Select } from 'base-ui-solid/select';
import styles from './index.module.css';

export default function ObjectValueSelect() {
  return (
    <div class={styles.Field}>
      <Select.Root defaultValue={shippingMethods[0]} itemToStringValue={(item) => item.id}>
        <Select.Label class={styles.Label}>Shipping method</Select.Label>
        <Select.Trigger class={styles.Select}>
          <Select.Value>
            {(method: ShippingMethod) => (
              <span class={styles.ValueText}>
                <span class={styles.ValuePrimary}>{method.name}</span>
                <span class={styles.ValueSecondary}>
                  {method.duration} ({method.price})

Grouped

Organize related options with <Select.Group> and <Select.GroupLabel> to add section headings inside the popup.

Groups are represented by an array of objects with an items property, which itself is an array of individual items for each group. An extra property, such as value, can be provided for the heading text when rendering the group label.

Example
interface ProduceGroupItem {
  value: string;
  items: string[];
}

const groups: ProduceGroupItem[] = [
  {
    value: 'Fruits',
    items: ['Apple', 'Banana', 'Orange'],
  },
  {
    value: 'Vegetables',
    items: ['Carrot', 'Lettuce', 'Spinach'],

Custom keyboard shortcuts

<Select.Root> accepts an actionsRef whose highlightItem() action moves the highlight to the 'next', 'previous', 'first' or 'last' item, or clears it with 'none'. Use it to bind shortcuts beyond the built-in arrow keys. Select items receive real DOM focus, so the action moves focus along with the highlight, and 'none' hands focus back to the popup. Select does not loop focus, so 'next' on the last item and 'previous' on the first one leave the highlight where it is. The action does nothing while the popup is closed.

Because the items hold focus while the popup is open, attach the key handler to <Select.Popup> rather than to the trigger:

Binding a shortcut on the popup
const actionsRef = { current: null as Select.Root.Actions | null };

<Select.Root actionsRef={actionsRef}>
  <Select.Trigger>
    <Select.Value />
  </Select.Trigger>
  <Select.Portal>
    <Select.Positioner>
      <Select.Popup
        onKeyDown={(event) => {
          if (event.ctrlKey && event.key === 'j') {
            event.preventDefault();
            actionsRef.current?.highlightItem('next');
          }
        }}
      >
        {/* items */}
      </Select.Popup>
    </Select.Positioner>
  </Select.Portal>
</Select.Root>;

API reference

Root

Groups all parts of the select. Doesn’t render its own HTML element.

Prop
Type
Default
namestring—
Identifies the field when a form is submitted.string
defaultValueUnion—
The uncontrolled value of the select when it’s initially rendered. To render a controlled select, use the value prop instead.Value[] | Value | null
valueUnion—
The value of the select. Use when controlled.Value[] | Value | null
onValueChangefunction—
Event handler called when the value of the select changes.((value: Value[] | Value | null, eventDetails: Select.Root.ChangeEventDetails) => void)
defaultOpenbooleanfalse
Whether the select popup is initially open. To render a controlled select popup, use the open prop instead.boolean
openboolean—
Whether the select popup is currently open.boolean
onOpenChangefunction—
Event handler called when the select popup is opened or closed.((open: boolean, eventDetails: Select.Root.OpenChangeEventDetails) => void)
highlightItemOnHoverbooleantrue
Whether moving the pointer over items should highlight them. Disabling this prop allows CSS :hover to be differentiated from the :focus (data-highlighted) state.boolean
actionsRefRefObject<Select.Root.Actions | 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.highlightItem: Moves or clears the highlight while the popup is open. 'next' and 'previous' move sequentially through the items and never wrap: the highlight stays on the last or first item. 'first' and 'last' highlight the first or last item. 'none' clears the highlight and hands focus back to the popup. Calling this action does not open the popup. To highlight an item after opening it, call the action from onOpenChangeComplete when open is true.RefObject<Select.Root.Actions | null>
autoCompletestring—
Provides a hint to the browser for autofill.string
formstring—
Identifies the form that owns the hidden input. Useful when the select is rendered outside the form.string
isItemEqualToValuefunction—
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.((itemValue: Value, value: Value) => boolean)
itemToStringLabelfunction—
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)
itemToStringValuefunction—
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.((itemValue: Value) => string)
itemsUnion—
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.Record<string, JSX.Element> | ({ label: JSX.Element; value: any })[] | Group[]
modalbooleantrue
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
multiplebooleanfalse
Whether multiple items can be selected.boolean
onOpenChangeCompletefunction—
Event handler called after any animations complete when the select popup is opened or closed.((open: boolean) => void)
disabledbooleanfalse
Whether the component should ignore user interaction.boolean
readOnlybooleanfalse
Whether the user should be unable to choose a different option from the select popup.boolean
requiredbooleanfalse
Whether the user must choose a value before submitting a form.boolean
inputRefRef<HTMLInputElement>—
A ref to access the hidden input element.Ref<HTMLInputElement>
