Anatomy

The Field family is designed for composing accessible forms. A typical field is structured as follows:

<Field.Field>
  <Field.Label for="input-id">Label</Field.Label>
  <!-- Input, Select, Switch, etc. -->
  <Field.Description>Optional helper text.</Field.Description>
  <Field.Error>Validation message.</Field.Error>
</Field.Field>

Field.Field is the core wrapper for a single field.
Field.Content is a flex column that groups label and description. Not required if you have no description.
Wrap related fields with Field.Group, and use Field.Set with Field.Legend for semantic grouping.

Responsive Layout

Vertical fields: Default orientation stacks label, control, and helper text—ideal for mobile-first layouts.
Horizontal fields: Set orientation="horizontal" on Field to align the label and control side-by-side. Pair with Field.Content to keep descriptions aligned.
Responsive fields: Set orientation="responsive" for automatic column layouts inside container-aware parents. Apply @container/field-group classes on Field.Group to switch orientations at specific breakpoints.

<script lang="ts">
  import * as Field from "$lib/components/ui/field/index.js";
  import { Button } from "$lib/components/ui/button/index.js";
  import { Input } from "$lib/components/ui/input/index.js";
</script>
 
<div class="w-full max-w-lg">
  <form>
    <Field.Set>
      <Field.Legend>Profile</Field.Legend>
      <Field.Description>Fill in your profile information.</Field.Description>
      <Field.Group>
        <Field.Field orientation="responsive">

            <Field.Label for="name">Name</Field.Label>
            <Field.Description
              >Provide your full name for identification</Field.Description

        <Field.Field orientation="responsive">
          <Button type="submit">Submit</Button>
          <Button type="button" variant="outline">Cancel</Button>
        </Field.Field>
      </Field.Group>
    </Field.Set>
  </form>
</div>

Validation and Errors

Add data-invalid to Field.Field to switch the entire block into an error state.
Add aria-invalid on the input itself for assistive technologies.
Render Field.Error immediately after the control or inside Field.Content to keep error messages aligned with the field.

<Field.Field data-invalid>
  <Field.Label for="email">Email</Field.Label>
  <Input id="email" type="email" aria-invalid />
  <Field.Error>Enter a valid email address.</Field.Error>
</Field.Field>

Accessibility

Field.Set and Field.Legend keep related controls grouped for keyboard and assistive tech users.
Field outputs role="group" so nested controls inherit labeling from Field.Label and Field.Legend when combined.
Apply Field.Separator sparingly to ensure screen readers encounter clear section boundaries.
