# Number Field

A high-quality, unstyled React number field component with increment and decrement buttons, and a scrub area.

## Demo

### Tailwind

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

```tsx

## Usage guidelines

- **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 component and assemble its parts:

```jsx title="Anatomy"
import { NumberField } from '@base-ui/react/number-field';

<NumberField.Root>
  <NumberField.ScrubArea>
    <NumberField.ScrubAreaCursor />
  </NumberField.ScrubArea>
  <NumberField.Group>
    <NumberField.Decrement />
    <NumberField.Input />
    <NumberField.Increment />
  </NumberField.Group>
</NumberField.Root>;
```

## API reference

### Root

Groups all parts of the number field and manages its state.
Renders a `<div>` element.

**Root Props:**

### ScrubAreaCursor

Renders a `<span>` element.

This component uses the [Pointer Lock API](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API), which may prompt the browser to display a related notification. It is disabled
in Safari to avoid a layout shift that this notification causes there.

| data-dirty     | -    | Present when the number field's value has changed (when wrapped in Field.Root).    |
| data-touched   | -    | Present when the number field has been touched (when wrapped in Field.Root).       |
| data-filled    | -    | Present when the number field is filled (when wrapped in Field.Root).              |
| data-focused   | -    | Present when the number field is focused (when wrapped in Field.Root).             |
