How can I implement custom validation with react-use-form-hook?

You can create custom validation by using the validate option in the useForm hook. Would you like an example?

Yes, please provide an example of custom validation.

Sure! You can define a validation function and pass it to the register method. For instance:

const { register, handleSubmit } = useForm();

const validateEmail = (value) => {
  return value.includes('@') ? true : 'Invalid email';
};

<input {...register('email', { validate: validateEmail })} />

What if I want to validate multiple fields?

You can create separate validation functions for each field and pass them similarly. Just ensure each field has its own validation logic.
