i have a form, with some custom fields.
I have for example, in the registration form, the possibility to choose for registration "For try" or "Definitive".
After the client have try and want to validate his registration definitively, i want he can go in the event frontend management and modify the field to "Definitive". It work, but i dont want he can modify the others fields.
I cant find a way to make readable only the fields i want.
