Event Handlers

Pass event handlers as props to the <Form> component to get access to the form at specific interaction points, including submission, errors, and more.

Custom event handlers, in the form of callback functions, are a powerful way for you to run custom code at critical moments when the user interacts with your Feathery form. They allow you to completely control and modify the default behavior of the form.
Pass your callback functions in directly as props of your <Form> component.
