API

`Field.Root`

Prop	Type	Default	Description
`id`*	`string`	—	Stable id every part passes back as fieldId, so label, control, description and error are wired together in the server markup.
`invalid`	`boolean`	`false`	Marks the field invalid, exposing data-invalid for styling.
`required`	`boolean`	`false`	Marks the field required, exposing data-required for styling.
`disabled`	`boolean`	`false`	Marks the field disabled, exposing data-disabled for styling.
`name`	`string`	—	Accepted for API compatibility; the name belongs on the control and is not rendered on the wrapper.
`render`	`ReactElement \| ((props, state) => ReactElement)`	—	Replace the rendered element while keeping behavior and accessibility wiring.

`Field.Label`

Prop	Type	Default	Description
`fieldId`*	`string`	—	The same id given to Field.Root, which resolves the htmlFor pointing at the control.
`disabled`	`boolean`	`false`	Marks the label disabled, exposing data-disabled for styling.
`required`	`boolean`	`false`	Marks the label required, exposing data-required for styling.

`Field.Control`

Prop	Type	Default	Description
`as`	`ElementType`	`"div"`	Use input, textarea, select or a custom control. Native props, event handlers, style and ref are forwarded.
`type / name / autoComplete / minLength / maxLength / pattern / readOnly`	`native control props`	—	Input options belong on Field.Control, including type="password". Standard validation and FormData semantics are preserved.
`fieldId`*	`string`	—	The same id given to Field.Root, which resolves the control id and its aria-labelledby and aria-describedby wiring.
`disabled`	`boolean`	`false`	Forwards native disabled to input, textarea and select and exposes data-disabled.
`invalid`	`boolean`	`false`	Sets aria-invalid and adds the error message to the control's aria-describedby.
`required`	`boolean`	`false`	Forwards native required to input, textarea and select, and sets aria-required.
`render`	`ReactElement \| ((props, state) => ReactElement)`	—	Replace the rendered element while keeping behavior and accessibility wiring.

`Field.Description`

Prop	Type	Default	Description
`fieldId`*	`string`	—	The same id given to Field.Root, which resolves the description id the control points at.
`disabled`	`boolean`	`false`	Marks the description disabled, exposing data-disabled for styling.

`Field.Error`

Prop	Type	Default	Description
`fieldId`*	`string`	—	The same id given to Field.Root, which resolves the error id the control points at when invalid.
`invalid`	`boolean`	`false`	Renders the error message; the part renders nothing while this is false.

Keyboard

Key	Action
`Tab`	Move focus to/from the control
`Enter` / `Space`	Activate when focused (button-like controls)

Accessibility

Uses semantic HTML where possible. Inspect rendered markup in the playground — ARIA is added only when native elements are insufficient.
