# Radio Group

Lets the user pick exactly one of a few options; joins the Field around it for its label, description and errors.

## Install

```sh
npx @frontic/ui add radio-group
```

Built from: [Use Field Control](https://ui.frontic.com/composables/use-field-control.md)

Used by: [Return Request](https://ui.frontic.com/components/sections/return-request.md)

npm packages: `@lucide/vue`, `@vueuse/core`, `reka-ui`

## Examples

```vue
<script setup lang="ts">
import { useId } from 'vue'
import { Field, FieldContent, FieldDescription, FieldLabel } from '@/components/ui/field'
import { RadioGroup, RadioGroupItem } from '@/components/ui/radio-group'

const id = useId()
</script>

<template>
  <Field>
    <FieldLabel :native-label="false">Delivery</FieldLabel>
    <RadioGroup default-value="standard">
      <Field orientation="horizontal">
        <RadioGroupItem :id="`${id}-standard`" value="standard" />
        <FieldContent>
          <FieldLabel :for="`${id}-standard`">Standard delivery</FieldLabel>
          <FieldDescription>Arrives in 3 to 5 working days. Free.</FieldDescription>
        </FieldContent>
      </Field>
      <Field orientation="horizontal">
        <RadioGroupItem :id="`${id}-express`" value="express" />
        <FieldContent>
          <FieldLabel :for="`${id}-express`">Express delivery</FieldLabel>
          <FieldDescription>Arrives the next working day.</FieldDescription>
        </FieldContent>
      </Field>
    </RadioGroup>
  </Field>
</template>
```

The example also uses `field`, which `add radio-group` leaves out: `npx @frontic/ui add field`.

## Anatomy

```vue
<RadioGroup>
  <RadioGroupItem />
</RadioGroup>
```

| Data attribute | Values | Description |
| --- | --- | --- |
| `data-disabled` |  | Present while the part is disabled. |

## API of the items the example uses

### Field

[Full docs](https://ui.frontic.com/components/ui/field.md) · `npx @frontic/ui add field`

#### Field

Groups a label, an input, a description and an error of one form field, and validates its input.

`data-slot="field"` · `Field.vue`

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `name` | `string` |  | The name of the field. Submitted with its owning form as part of a name/value pair, and used to match server `errors` on a `FormRoot`. Takes precedence over the `name` of the control. |
| `disabled` | `boolean` | `false` | When `true`, prevents the user from interacting with the field's control. Takes precedence over the `disabled` of the control. |
| `required` | `boolean` | `false` | When `true`, indicates that the user must set the value before the owning form can be submitted. |
| `invalid` | `boolean` |  | When `true`, marks the field invalid regardless of its own validation. Useful when the field state is controlled by an external library. |
| `dirty` | `boolean` |  | Whether the field's value has changed from its initial value. Useful when the field state is controlled by an external library. |
| `touched` | `boolean` |  | Whether the field has been touched (its control blurred). Useful when the field state is controlled by an external library. |
| `validate` | `FieldValidateFn`: `(value: unknown, formValues: Record<string, unknown>): FieldValidateResult \| Promise<FieldValidateResult>` |  | Custom validation function. Return an error message (or array of messages) when invalid, or `null`/`undefined` when valid. Receives the control's value and the values of every named field in the owning form.<br><br>Can be async, but an async `validate` does not prevent form submission when `validationMode` is `onSubmit`. |
| `validationMode` | `FieldValidationMode`: `'onBlur' \| 'onChange' \| 'onSubmit'` | `'onSubmit'` | When the field (re-)runs validation. Takes precedence over the `validationMode` of an ancestor `FormRoot`.<br>- `onSubmit`: when the form is submitted, then on every change after that.<br>- `onBlur`: when the control loses focus.<br>- `onChange`: on every change to the control's value. |
| `validationDebounceTime` | `number` |  | How long to wait (in ms) between `validate` calls when validating on change. |
| `asChild` | `boolean` | `false` | Change the default rendered element for the one passed as a child, merging their props and behavior.<br><br>Read our [Composition](https://www.reka-ui.com/docs/guides/composition) guide for more details. |
| `as` | `AsTag \| Component`: `ComponentOptions<any, any, any, ComputedOptions, MethodOptions, any, any, any, string, {}, {}, string, {}, {}, {}, string, ComponentProvideOptions> \| (props: any, ctx: Omit<{ attrs: Attrs; slots: Readonly<InternalSlots>; emit: (event: string, ...args: any[]) => void; expose: <Exposed extends Record<string, any> = Record<string, any>>(exposed?: Exposed \| undefined) => void; }, 'expose'>): any \| ComponentPublicInstanceConstructor<any, any, any, any, ComputedOptions, MethodOptions> \| 'a' \| 'button' \| 'div' \| 'form' \| 'h2' \| 'h3' \| 'img' \| 'input' \| 'label' \| 'li' \| 'nav' \| 'ol' \| 'p' \| 'span' \| 'svg' \| 'ul' \| 'template' \| {} & string` |  | The element or component this component should render as. Can be overwritten by `asChild`. |
| `class` | `ClassValue` |  | Classes added to the part's own element, after its recipe classes. |
| `orientation` | `FieldOrientation`: `'vertical' \| 'horizontal' \| 'responsive'` | `'vertical'` | Label above the control, beside it, or `responsive`: beside it once the field group is wide enough. |

| Slot | Slot props | Description |
| --- | --- | --- |
| `default` | `{ invalid: boolean; errors: string[]; }` | The label, control, description and error; gets `invalid` and the current `errors`. |

| Data attribute | Values | Description |
| --- | --- | --- |
| `data-horizontal` |  | Present when the part is laid out horizontally. |
| `data-orientation` | `'vertical' \| 'horizontal' \| 'responsive'` | Carries the `orientation` prop. |

#### FieldContent

Groups the label and description that sit beside the control of a field. Renders a `<div>`.

`data-slot="field-content"` · `FieldContent.vue`

`data-slot="field-description"` · `FieldDescription.vue`

Styling: `field-description`, which extends [`hint`](https://ui.frontic.com/DESIGN.md#hint) and [`link-primary`](https://ui.frontic.com/DESIGN.md#link-primary). Change them there and every part that extends them follows.

Styling: `field-error`, which extends [`error`](https://ui.frontic.com/DESIGN.md#error). Change it there and every part that extends it follows.

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `id` | `string` |  | Id of the element. Auto-generated when not provided. |

| `forceMount` | `boolean` | `false` | Used to force mounting when more control is needed. Useful when controlling animation with Vue animation libraries. |
| `asChild` | `boolean` | `false` | Change the default rendered element for the one passed as a child, merging their props and behavior.<br><br>Read our [Composition](https://www.reka-ui.com/docs/guides/composition) guide for more details. |
| `as` | `AsTag \| Component`: `ComponentOptions<any, any, any, ComputedOptions, MethodOptions, any, any, any, string, {}, {}, string, {}, {}, {}, string, ComponentProvideOptions> \| (props: any, ctx: Omit<{ attrs: Attrs; slots: Readonly<InternalSlots>; emit: (event: string, ...args: any[]) => void; expose: <Exposed extends Record<string, any> = Record<string, any>>(exposed?: Exposed \| undefined) => void; }, 'expose'>): any \| ComponentPublicInstanceConstructor<any, any, any, any, ComputedOptions, MethodOptions> \| 'a' \| 'button' \| 'div' \| 'form' \| 'h2' \| 'h3' \| 'img' \| 'input' \| 'label' \| 'li' \| 'nav' \| 'ol' \| 'p' \| 'span' \| 'svg' \| 'ul' \| 'template' \| {} & string` |  | The element or component this component should render as.

| --- | --- | --- | --- |
| `nativeLabel` | `boolean` | `true` | Whether the label renders a native `label` element.
