actions.batchEditElements([
{
fieldIndex: 0,
modifiedFormElement: { required: true }
},
{
fieldIndex: 1,
modifiedFormElement: { required: true }
},
{
fieldIndex: 2,
modifiedFormElement: { required: true, type: "email" }
}
]);
};

},
{
type: "edit",
options: {
fieldIndex: 0,
modifiedFormElement: { placeholder: "Enter username" }
}
}
]);
};
// Convert to multi-step and add steps in batch
const createMultiStepForm = () => {
batch.formOperations.convertToMultiStepAndAddSteps(3);
// Creates 3-step form in single operation
};
return (
);
}
