BuddyPress.org

So, yes, by default, the register page only shows group 1 (the “base” group). You only retrieve one group via the profile_group_id= parameter in the bp_has_profile() call.

So, by default, this happens:

What I’m trying to accomplish is to hide groups 3 and 4 on the registration page not to overwhelm the user with a bunch of fields to fill out during sign-up, those fields can be filled out once the user has activated her/his account via “edit profile”.

There have been other threads on the forum regarding showing more than one profile group on the registration page; I found several, but take a look at https://buddypress.org/forums/topic/all-fields-for-registration. It’s probably going to be really difficult to implement unless you have a decent understanding of PHP.
