`Radio` represents one option inside [RadioGroup](/ui/primitives/input/radio-group). Give each option a distinct `value` and a visible label. The group owns the selected value.

## Labeled options

```tsx
import { Radio, RadioGroup } from 'twenty-ui/primitives/input';

export const ContactMethod = () => (
  <RadioGroup
    name="contactMethod"
    defaultValue="email"
    aria-label="Preferred contact method"
  >
    <label>
      <Radio value="email" />
      Email
    </label>
    <label>
      <Radio value="phone" />
      Phone
    </label>
    <label>
      <Radio value="post" disabled />
      Postal mail (unavailable)
    </label>
  </RadioGroup>
);
```

The `size` prop accepts `sm` or `md` and defaults to `sm`. Use the same size for options in a group.

## Keyboard and selection

Tab enters or leaves the group. Arrow keys move between enabled options and select the focused option. Space selects the focused radio. Selection and change handlers belong on `RadioGroup`; see its [uncontrolled example](/ui/primitives/input/radio-group#uncontrolled-state) and [controlled example](/ui/primitives/input/radio-group#controlled-state).

`Radio` is generic over the value type. Keep that type consistent with its group. Native attributes such as `aria-describedby` can associate an option with additional help text.

## Props

The reference is generated from the public component types. Native attributes, including accessible names and event handlers, are also accepted on parts that render elements.
