## Usage guidelines
- **Avoid when selection state is needed**: Use [Combobox](/react/components/combobox.md) instead of Autocomplete if the selection should be remembered and the input value cannot be custom. Unlike Combobox, Autocomplete's input can contain free-form text, as its suggestions only _optionally_ autocomplete the text.
- **Can be used for filterable command pickers**: The input can be used as a filter for command items that perform an action when clicked when rendered inside the popup.
- **Form controls must have an accessible name**: It can be created using a `<label>` element or the `Field` component. See the [forms guide](/react/handbook/forms.md).
## Anatomy
Import the components and place them together:
```jsx title="Anatomy"
import { Autocomplete } from '@base-ui/react/autocomplete';
<Autocomplete.Root>
<Autocomplete.InputGroup>
<Autocomplete.Input />
<Autocomplete.Trigger />
<Autocomplete.Icon />
<Autocomplete.Clear />
<Autocomplete.Value />
</Autocomplete.InputGroup>
<Autocomplete.Portal>
<Autocomplete.Backdrop />
<Autocomplete.Positioner>
<Autocomplete.Popup>
<Autocomplete.Arrow />
<Autocomplete.Status />
<Autocomplete.Empty />
<Autocomplete.List>
<Autocomplete.Row>
<Autocomplete.Item />
</Autocomplete.Row>
<Autocomplete.Separator />
<Autocomplete.Group>
<Autocomplete.GroupLabel />
</Autocomplete.Group>
<Autocomplete.Collection />
</Autocomplete.List>
</Autocomplete.Popup>
</Autocomplete.Positioner>
</Autocomplete.Portal>
</Autocomplete.Root>;
```
## TypeScript inference
Autocomplete infers the item type from the `items` prop passed to `<Autocomplete.Root>`.
If using `itemToStringValue`, the value prop on the `<Autocomplete.Item>` must match the type of an item in the `items` array.
## Examples
### Async search
Load items asynchronously while typing and render custom status content.

### Tailwind

### Grouped
Organize related options with `<Autocomplete.Group>` and `<Autocomplete.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.
```tsx title="Example"
interface ProduceGroupItem {
value: string;
// @highlight
items: string[];
}
const groups: ProduceGroupItem[] = [
{
value: 'Fruits',
// @highlight
items: ['Apple', 'Banana', 'Orange'],
},
{
value: 'Vegetables',
// @highlight
items: ['Carrot', 'Lettuce', 'Spinach'],
},
];
```
## Demo
### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
'use client';
import { Autocomplete } from '@base-ui/react/autocomplete';
export default function ExampleGroupAutocomplete() {
return (
<Autocomplete.Root items={groupedTags}>
<label className="flex flex-col gap-1
