How to split out BuddyPress notifications drop down items to their own top

Hi, I have gotten some help on this in this thread:
how-to-split-out-buddypress-notifications-drop-down-items-to-their-own-top-level
But have yet to get the drop-down menus right. Is there anyone here that can help me? I would like to split out the notifications similar to facebooks. I have scoured the codex and google trying to find the solution but I haven’t found any documentation in how to do this. I know there is a premium plugin that does this but at the moment I cannot afford it so any help will be greatly appreciated. Thanks everyone! ??
