useObjectField

Creates a form based on another form’s field. Use this with nested objects. This hook does not cause a rerender.

This hook must be called, unconditionally, at the start of your component, just like the normal React hooks.

If your field can/will be null or undefined, you should use the ObjectField component instead, which does not render when the field is null/undefined.

useObjectField(parentForm, name)

Parameters

parentForm (required)

The parent form that contains the field to create a child form for.

name (required)

The name of a field in the parent form to create a child form for.

Returns

A ChildFormState object.

Usage

See Object fields for useful examples.
