How can I use the useForm hook in React for complex forms?

You can use the useForm hook from react-hook-form to manage complex forms by leveraging its features like validation, nested fields, and dynamic inputs.

Can you show me an example of handling nested fields?

Sure! You can define nested fields in your form data structure and use the register method to bind them. Here's a quick example:

const { register } = useForm();

return (
  <form>
    <input {...register('user.name')} placeholder='Name' />
    <input {...register('user.email')} placeholder='Email' />
  </form>
);

What about validation for these nested fields?

You can add validation rules directly in the register method. For example:

<input {...register('user.name', { required: true })} placeholder='Name' />

This will ensure that the name field is required.

How do I handle dynamic fields that can be added or removed?

You can use the useFieldArray hook from react-hook-form to manage dynamic fields. It allows you to add or remove fields easily.
