Field visibility add-on allows you to show or hide certain fields on the front-end registration form or the User’s Profile page. Admin can hide fields to break a single form into parts. This is most useful when you don’t want to overwhelm the user and want the fields to be displayed step by step during the registration and hide them later, or vice versa. Admin can also enable the fields to be Read-only on the registration form, the profile page, or both to restrict users from changing the details once they have filled them.
