How can I manage nested fields in React Hook Form?

How can I manage nested fields in React Hook Form?

You can manage nested fields in React Hook Form by using the useForm hook along with the register method for each nested field.

Can you show me an example of how to set this up?

Sure! You can create a form structure like this:

const { register, handleSubmit } = useForm();

<form onSubmit={handleSubmit(onSubmit)}>
  <input {...register('user.name')} placeholder='Name' />
  <input {...register('user.age')} placeholder='Age' />
  <input {...register('user.address.street')} placeholder='Street' />
  <input {...register('user.address.city')} placeholder='City' />
  <button type='submit'>Submit</button>
</form>

What if I want to dynamically add more nested fields?

You can use the useFieldArray hook from React Hook Form to dynamically add or remove nested fields. This allows for a more flexible form structure.
