@shmk profile fields you add in the Base Field Group shows up in the Registration Form https://codex.buddypress.org/administrator-guide/extended-profiles/
I know that Base group are shown in the Registration Form, but I have to add over 30 fields during registration so if they could be logically separated from the base group during registration and inside the user profile would be of great help for the customer.

@shmk thanks for confirming, just had to make sure you did. There’s a trac ticket which needs some more work done to get the feature you want at https://buddypress.trac.wordpress.org/ticket/6347
Thanks @mercime for the link, I’ll follow the progress of the issue.
In the meantime do you know if there are any plugins that permit to edit the BuddyPress registration page?
This thread may have the solution to your answer. I used information here to display all Groups to my registration page and have them populate my DB.
