I'd like to assign a user to a custom group instead a some standard Joomla group, based on a dropdown choice. I've created a user group named "students". Then I added a new custom custom field for the registration form (it's just one for everyone). The custom field is a dropdown and if the user select "yes", I want that at the end of the registration it'll be automatically assigned to the "students" group instead of the guests. Any help would be really appreciated! :)
Thank you all!
