Use with other form controls

Warning

Form controls must have an accessible name in order to be recognized by assistive technologies. <FieldLabel> and <FieldDescription> automatically assign the accessible name and description to their associated control.

Select

Note

You can implicitly label <Checkbox>, <Radio> and <Switch> components by enclosing them with <FieldLabel>. See below Checkbox example.

Checkbox

Fieldset

Radio Group

Autocomplete

API Reference

Component	Description
`Field`	Groups all parts of the field. Renders a `<div>` element.
`FieldLabel`	An accessible label that is automatically associated with the field control. Renders a `<label>` element.
`FieldControl`	The form control to label and validate. Renders an `<input>` element. You can omit this part and use any Base UI input component instead. For example, Input, Checkbox, or Select, among others, will work with Field out of the box.
`FieldDescription`	A paragraph with additional information about the field. Renders a `<p>` element.
`FieldItem`	Groups individual items in a checkbox group or radio group with a label and description. Renders a `<div>` element.
`FieldError`	An error message displayed if the field control fails validation. Renders a `<div>` element.
`FieldValidity`	Used to display a custom message based on the field’s validity. Requires children to be a function that accepts field validity state as an argument.
