## Examples

```vue
<script setup lang="ts">
import { computed, ref, useId } from 'vue'
import { Field, FieldContent, FieldDescription, FieldLabel, FieldLegend, FieldSeparator, FieldSet } from '@/components/ui/field'
import { Checkbox } from '@/components/ui/checkbox'

const id = useId()
const topics = [
  { key: 'arrivals', name: 'New arrivals', detail: 'The season’s first jackets, goggles and packs, the week they land.' },

const picked = ref<string[]>(['arrivals'])

const all = computed(() => (picked.value.length === topics.length ? true : picked.value.length ? 'indeterminate' : false))
const toggleAll = () => (picked.value = all.value === true ? [] : topics.map((topic) => topic.key))
const toggle = (key: string, on: boolean | 'indeterminate') => (picked.value = on === true ? [...picked.value, key] : picked.value.filter((k) => k !== key))
</script>

<template>
  <FieldSet class="w-xl max-w-full">
    <FieldLegend>Newsletter</FieldLegend>
    <div class="flex flex-col gap-3">
      <Field orientation="horizontal">
        <Checkbox :id="`${id}-all`" :model-value="all" @update:model-value="toggleAll" />
        <FieldLabel :for="`${id}-all`">All newsletters</FieldLabel>
      </Field>
      <FieldSeparator />
      <div class="flex flex-col gap-3">
        <Field v-for="topic in topics" :key="topic.key" orientation="horizontal">
          <Checkbox :id="`${id}-${topic.key}`" :model-value="picked.includes(topic.key)" @update:model-value="(on) => toggle(topic.key, on)" />

| --- | --- | --- |
| `update:modelValue` | `value: boolean \| "indeterminate"` | Event handler called when the value of the checkbox changes. |

| Slot | Slot props | Description |

## 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. |

| `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.
