# Picker

A single-selection input with menu and wheel appearances.
Android, iOS, Web, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

`Picker` is a single-selection input. You can use `<Picker.Item label value />` children to declare options so that the parent `Picker` reads them and renders a platform-appropriate dropdown or rotor.

The universal `Picker` is independent of [`@expo/ui/community/picker`](/versions/v56.0.0/sdk/ui/drop-in-replacements/picker), which remains a compat shim for `@react-native-picker/picker`. Prefer this universal `Picker` for new code unless you specifically need the RN-Picker API surface.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Menu appearance (default)

```tsx
import { useState } from 'react';
import { Host, Row, Picker, Spacer, Text } from '@expo/ui';

const FLAVOURS = [
  { label: 'Vanilla', value: 'vanilla' },
  { label: 'Chocolate', value: 'chocolate' },
  { label: 'Strawberry', value: 'strawberry' },
];

export default function PickerMenuExample() {
  const [value, setValue] = useState('vanilla');

  return (
    <Host style={{ flex: 1 }}>
      <Row alignment="center" spacing={12} style={{ padding: 16 }}>
        <Text>Flavour:</Text>
        <Spacer flexible />
        <Picker selectedValue={value} onValueChange={setValue}>
          {FLAVOURS.map(f => (
            <Picker.Item key={f.value} label={f.label} value={f.value} />
          ))}
        </Picker>
      </Row>
    </Host>
  );
}
```

### Wheel appearance

`appearance="wheel"` renders an inline scrollable rotor on iOS. On Android and web, this falls back to the platform's default dropdown (Material 3 doesn't ship a wheel-style picker).

```tsx
import { useState } from 'react';
import { Host, Column, Picker } from '@expo/ui';

const FLAVOURS = [
  { label: 'Vanilla', value: 'vanilla' },
  { label: 'Chocolate', value: 'chocolate' },
  { label: 'Strawberry', value: 'strawberry' },
];

export default function PickerWheelExample() {
  const [value, setValue] = useState('chocolate');

  return (
    <Host style={{ flex: 1 }}>
      <Column spacing={8} style={{ padding: 16 }}>
        <Picker selectedValue={value} onValueChange={setValue} appearance="wheel">
          {FLAVOURS.map(f => (
            <Picker.Item key={f.value} label={f.label} value={f.value} />
          ))}
        </Picker>
      </Column>
    </Host>
  );
}
```
