BuddyPress.org

@roadblock – I’m not sure I understand what you need to do. Can you explain a bit more. you can use the bp_has_groups() (https://codex.buddypress.org/developer-docs/custom-buddypress-loops/the-groups-loop/) to display groups and pass a variable to it in three ways as an $bp->current_action which is just a url such as groups/myaction/ or you can use ajax to send a query string (kinda complex) or you can use the $_POST variable. Custom groups lists are kinda messy in Buddypress and not easy to implement, I kind of hacked this usability together. good luck.
