Skip to main content
Use Field to group one control with its accessible label and helper text. Components such as Input integrate with the field directly.

Labeled control

Field.Root manages the control’s name, disabled state, and validity. Field.Label and Field.Description connect their content to the control. Set validation timing with validationMode; use validate for custom validation.

External errors

Use invalid when your application owns the error state. An explicit match makes the error message visible.

Parts

Keep error messages actionable and provide a visible label even when the control has a placeholder.

Props

The reference is generated from the public component types. Native attributes, including accessible names and event handlers, are also accepted on parts that render elements.

Field.Root

RefObject<FieldRootActions | null>
A ref to imperative actions.
  • validate: Validates the field when called.
string | ((state: FieldRootState) => string | undefined)
CSS class applied to the element, or a function that returns a class based on the component’s state.
boolean
Whether the field’s value has been changed from its initial value. Useful when the field state is controlled by an external library.
boolean
default:"false"
Whether the component should ignore user interaction. Takes precedence over the disabled prop on the <Field.Control> component.
boolean
Whether the field is invalid. Useful when the field state is controlled by an external library.
string
Identifies the field when a form is submitted. Takes precedence over the name prop on the <Field.Control> component.
ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, FieldRootState>
Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.
CSSProperties | ((state: FieldRootState) => CSSProperties | undefined)
Style applied to the element, or a function that returns a style object based on the component’s state.
boolean
Whether the field has been touched. Useful when the field state is controlled by an external library.
((value: unknown, formValues: Record<string, any>) => string | void | string[] | Promise<string | void | string[] | null> | null)
A function for custom validation. Return a string or an array of strings with the error message(s) if the value is invalid. Returning nothing, null, an empty string, or an empty array means the value is valid. Asynchronous functions are supported, but they do not prevent form submission when using validationMode="onSubmit".
number
default:"0"
How long to wait between validate callbacks if validationMode="onChange" is used. Specified in milliseconds.
"onBlur" | "onChange" | "onSubmit"
default:"onSubmit"
Determines when the field should be validated. This takes precedence over the validationMode prop on <Form>.
  • onSubmit: triggers validation when the form is submitted, and re-validates on change after submission.
  • onBlur: triggers validation when the control loses focus.
  • onChange: triggers validation on every change to the control value.

Field.Label

string | ((state: FieldLabelState) => string | undefined)
CSS class applied to the element, or a function that returns a class based on the component’s state.
boolean
default:"true"
Whether the component renders a native <label> element when replacing it via the render prop. Set to false if the rendered element is not a label (for example, <div>).This is useful to avoid inheriting label behaviors on <button> controls (such as <Select.Trigger> and <Combobox.Trigger>), including avoiding :hover on the button when hovering the label, and preventing clicks on the label from firing on the button.
ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, FieldLabelState>
Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.
CSSProperties | ((state: FieldLabelState) => CSSProperties | undefined)
Style applied to the element, or a function that returns a style object based on the component’s state.

Field.Control

string | ((state: FieldControlState) => string | undefined)
CSS class applied to the element, or a function that returns a class based on the component’s state.
string | number | readonly string[]
((value: string, eventDetails: { reason: "none"; event: Event; cancel: () => void; allowPropagation: () => void; isCanceled: boolean; isPropagationAllowed: boolean; trigger: Element | undefined; }) => void)
Callback fired when the value changes. Use when controlled.
ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, FieldControlState>
Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.
CSSProperties | ((state: FieldControlState) => CSSProperties | undefined)
Style applied to the element, or a function that returns a style object based on the component’s state.

Field.Description

string | ((state: FieldDescriptionState) => string | undefined)
CSS class applied to the element, or a function that returns a class based on the component’s state.
ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, FieldDescriptionState>
Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.
CSSProperties | ((state: FieldDescriptionState) => CSSProperties | undefined)
Style applied to the element, or a function that returns a style object based on the component’s state.

Field.Error

string | ((state: FieldErrorState) => string | undefined)
CSS class applied to the element, or a function that returns a class based on the component’s state.
boolean | keyof ValidityState
Determines whether to show the error message according to the field’s ValidityState. Specifying true will always show the error message, and lets external libraries control the visibility.
ReactElement<unknown, string | JSXElementConstructor<any>> | ComponentRenderFn<HTMLProps, FieldErrorState>
Allows you to replace the component’s HTML element with a different tag, or compose it with another component.Accepts a ReactElement or a function that returns the element to render.
CSSProperties | ((state: FieldErrorState) => CSSProperties | undefined)
Style applied to the element, or a function that returns a style object based on the component’s state.

Field.Validity

(state: FieldValidityState) => ReactNode
required
A function that accepts the field validity state as an argument.
