onCustomAction is a <Feathery.Form> prop and callback function to access and modify form state when a button that is configured to trigger a custom action is clicked. When a custom action is performed, step navigation is not triggered. If you want to trigger navigation, consider configuring the skip action. This function can be asynchronous.


You can use onCustomAction to apply custom form navigation, render a custom component, set form state, and more.

import { init, Form } from 'feathery-react';
function App() {
// Initialize Feathery to Peter
init('adminAPIKey', 'peter@feathery.io');
// Show the `onboarding` Feathery form
return <Form
// Route to a specific step
onCustomAction={(context) => {
context.setStep("Custom Step");
