Re: Is it possible to do this?
Install Custom Profile Filters for BuddyPress: https://buddypress.org/community/groups/custom-profile-filters-for-buddypress/
Add a select box to the base field group in your Buddypress profile field setup with the different selections: dj, musician, producer, etc. Make sure this is in the base group so users must select one when registering. Follow the instructions in the plugin to turn each selection into a search link.
When you click on any of the selected labels in a user’s profile, that brings you to the members directory but displays only the users who have also selected the same.
Hope this helps!
