A wrapper for form elements that provides validation and error handling.

Usage

Wrap any form component with a FormField. Used in a Form, it provides validation and error handling.

Label

Use the label prop to set the label for the form control.

<template>
  <UFormField label="Email">
    <UInput placeholder="Enter your email" />
  </UFormField>
</template>
The label for attribute and the form control are associated with a unique id if not provided.

When using the required prop, an asterisk is be added next to the label.

<template>
  <UFormField label="Email" required>
    <UInput placeholder="Enter your email" />
  </UFormField>
</template>

Description

Use the description prop to provide additional information below the label.

We'll never share your email with anyone else.

<template>
  <UFormField
    label="Email"
    description="We'll never share your email with anyone else."
  >
    <UInput placeholder="Enter your email" class="w-full" />
  </UFormField>
</template>

Hint

Use the hint prop to display a hint message next to the label.

Optional
<template>
  <UFormField label="Email" hint="Optional">
    <UInput placeholder="Enter your email" />
  </UFormField>
</template>

Help

Use the help prop to display a help message below the form control.

Please enter a valid email address.

<template>
  <UFormField label="Email" help="Please enter a valid email address.">
    <UInput placeholder="Enter your email" class="w-full" />
  </UFormField>
</template>

Error

Use the error prop to display an error message below the form control. When used together with the help prop, the error prop takes precedence.

When used inside a Form, this is automatically set when a validation error occurs.

Please enter a valid email address.

<template>
  <UFormField label="Email" error="Please enter a valid email address.">
    <UInput placeholder="Enter your email" class="w-full" />
  </UFormField>
</template>
This sets the color to error on the form control. You can change it globally in your app.config.ts.

Size

Use the size prop to change the size of the FormField, the size is proxied to the form control.

Optional

We'll never share your email with anyone else.

Please enter a valid email address.

<template>
  <UFormField
    label="Email"
    description="We'll never share your email with anyone else."
    hint="Optional"
    help="Please enter a valid email address."
    size="xl"
  >
    <UInput placeholder="Enter your email" class="w-full" />
  </UFormField>
</template>
