# Filter Select

A high-quality, unstyled React select component with a built-in input for filtering options.

## Demo

### Tailwind

This example shows how to implement the component using Tailwind CSS.

```tsx
/* index.tsx */
'use client';
import * as React from 'react';
import { FilterSelect } from '@base-ui/react/filter-select';

const fruits = [
  { value: 'apple', label: 'Apple' },
  { value: 'apricot', label: 'Apricot' },
  { value: 'banana', label: 'Banana' },
  { value: 'blueberry', label: 'Blueberry' },
  { value: 'cherry', label: 'Cherry' },
  { value: 'grape', label: 'Grape' },
  { value: 'kiwi', label: 'Kiwi' },
  { value: 'mango', label: 'Mango' },
  { value: 'orange', label: 'Orange' },
  { value: 'peach', label: 'Peach' },
  { value: 'pear', label: 'Pear' },
  { value: 'pineapple', label: 'Pineapple' },
  { value: 'strawberry', label: 'Strawberry' },
];

export default function FilterSelectDemo() {

## Usage guidelines

- **Use for modest option lists**: Choose `FilterSelect` when users select one or more predefined values and need search to narrow a manageable list. Use [Select](/react/components/select.md) when search is unnecessary.
- **Prefer Combobox for large or remote data**: Use [Combobox](/react/components/combobox.md) when the input is the control or the list is large, virtualized, or asynchronously loaded. Use [Autocomplete](/react/components/autocomplete.md) when users can enter values that are not in the list.
- **Name both controls**: `<FilterSelect.Label>` labels the select trigger. Give `<FilterSelect.Input>` a separate accessible name with `aria-label`, `aria-labelledby`, or a visible native `<label>`.

## Anatomy

Import the component and assemble its parts:

```jsx title="Anatomy"
import { FilterSelect } from '@base-ui/react/filter-select';

<FilterSelect.Root items={items}>
  <FilterSelect.Label>Fruit</FilterSelect.Label>
  <FilterSelect.Trigger>
    <FilterSelect.Value placeholder="Choose a fruit" />
    <FilterSelect.Icon />
  </FilterSelect.Trigger>

  <FilterSelect.Portal>
    <FilterSelect.Positioner>
      <FilterSelect.Popup>
        <FilterSelect.Input aria-label="Filter fruit" />
        <FilterSelect.Clear aria-label="Clear filter" />
        <FilterSelect.Empty>No fruit found.</FilterSelect.Empty>
        <FilterSelect.List>
          {(item) => (
            <FilterSelect.Item key={item.value} value={item.value}>
              {item.label}
            </FilterSelect.Item>
          )}
        </FilterSelect.List>
      </FilterSelect.Popup>
    </FilterSelect.Positioner>
  </FilterSelect.Portal>
</FilterSelect.Root>;
```

`items` is required because it is the data source used to filter the list. Render the items with a function child of `<FilterSelect.List>` so the rendered entry stays associated with its data.

## Examples

### Rendering from items

`items` can be an array of entries, an object map, or grouped entries. Each entry has a `value` and `label`:

```jsx title="Rendering options"
const items = [
  { value: 'apple', label: 'Apple' },
  { value: 'banana', label: 'Banana' },
];

<FilterSelect.Root items={items}>
  <FilterSelect.List>
    {(item) => (
      <FilterSelect.Item key={item.value} value={item.value}>
        {item.label}
      </FilterSelect.Item>
    )}
  </FilterSelect.List>
</FilterSelect.Root>;
```

### Matching keywords

Add `keywords` to an item when users should be able to find it using terms that are not displayed in its label:

```jsx title="Additional search terms"
const items = [{ value: 'settings', label: 'Settings', keywords: ['preferences', 'options'] }];
```

The default filter matches the entry's label and its keywords. Keywords are not rendered as part of the option.

### Custom matching

Pass `filter` to change how entries match the query. The callback receives the item from `items` and the trimmed query. Parameterize `FilterSelectFilter` with the item type when declaring a reusable filter:

```tsx title="Custom filter"
import type { FilterSelectFilter, FilterSelectItemData } from '@base-ui/react/filter-select';

interface Fruit extends FilterSelectItemData<string> {
  category: string;
}

const filter: FilterSelectFilter<Fruit> = (item, query) => item.category === query;

<FilterSelect.Root items={items} filter={filter}>
  {/* select parts */}
</FilterSelect.Root>;
```

When a custom filter is provided, it is authoritative. Inspect `item.keywords` inside it if they should also match.

### Controlled query

Use `inputValue` and `onInputValueChange` when the query needs to be synchronized with application state. `defaultInputValue` sets the initial query for uncontrolled usage.

```tsx title="Controlling the query"
import * as React from 'react';
import { FilterSelect } from '@base-ui/react/filter-select';

function SearchableSelect() {
  const [inputValue, setInputValue] = React.useState('');

  return (
    <FilterSelect.Root
      items={items}
      inputValue={inputValue}
      onInputValueChange={(value) => setInputValue(value)}
    >
      {/* select parts */}
    </FilterSelect.Root>
  );
}
```

The query is cleared when the popup closes. If the query is controlled, update the value in `onInputValueChange` for the clear and close events as well as for typing.

### Grouped options

Use grouped entries with `<FilterSelect.Group>`, `<FilterSelect.GroupLabel>`, and `<FilterSelect.Collection>`:

```jsx title="Grouped options"
<FilterSelect.List>
  {(group) => (
    <FilterSelect.Group key={group.value} items={group.items}>
      <FilterSelect.GroupLabel>{group.value}</FilterSelect.GroupLabel>
      <FilterSelect.Collection>
        {(item) => (
          <FilterSelect.Item key={item.value} value={item.value}>
            {item.label}
          </FilterSelect.Item>
        )}
      </FilterSelect.Collection>
    </FilterSelect.Group>
  )}
</FilterSelect.List>
```

Groups with no matching options are removed from the rendered list.
