## Documentation
## Usage
A set of radio buttons where exactly one can be selected at a time.
The simplest way is to pass an `options` array — items, labels, and spacing are handled for you:
```svelte
```
## With descriptions
Each option can carry an optional `description`:
```svelte
```
## Horizontal layout
```svelte
```
## Custom rendering
For full control, skip `options` and compose with `RadioGroupItem`:
```svelte
Option Two
```
## Sources
This component uses the bits-ui component: RadioGroup, see here for the documentation for that: https://bits-ui.com/docs/components/radio-group/llms.txt
## API Reference
### RadioGroup
A set of radio buttons where exactly one can be selected. Pass an `options` array for the common case, or use `RadioGroupItem` as children for custom layouts.
| Prop | Type | Default | Description |
|------|------|---------|-------------|
| value | `string` | `''` | The currently selected value. (bindable) |
| options | `RadioGroupOption[]` | `-` | Array of options rendered as radio items with labels. Each option is `{ value, label?, description?, disabled? }`. Omit to compose children manually. |
| variant | `'primary' | 'secondary'` | `'primary'` | Color variant applied to every item. |
| sizeVariant | `'default' | 'sm' | 'lg'` | `'default'` | Size applied to every item. |
| orientation | `'vertical' | 'horizontal'` | `'vertical'` | Layout direction when rendering the options array. |
| disabled | `boolean` | `-` | Disable the entire group. |
| onValueChange | `(value: string) => void` | `-` | Callback when the selected value changes. |
| children | `Snippet` | `-` | Custom content (e.g. `RadioGroupItem`s). Ignored if `options` is provided. |
| class | `string` | `-` | Additional CSS classes on the group container. |
