Lol, 🙂 well now your asking for the whole boxed lunch, lol.
Um well ok, lets see here.
first I created a bp-templates directory in my themes buddypress directory. I then created a file called login widget. On that file I went to bootstraps modal and added that in there and then simply broke down the buddypress login form into it.
I called this into my main nav area using get_template_part in a <a href link. Its kind of time consuming but its really easy to do. To try to break it down piece by piece would take a while.
