Drop down menu for sub-forums

[JonathanC]

I currently have the following template modification on my website:
http://xenforo.com/community/threads/tutorial-sub-forum-grid-listing.10978/

I've made code edits to remove the sub-forums showing up like this:

Instead I would like the Sub-forums to show in a drop down menu on the master forum. I've messed around with it for a few hours today, and it was unsuccessful. I would appreciate some suggestions or solutions.

They are in a menu by default. Do you mean a menu elsewhere?

I have these forums, that have sub forums. I've removed the function that shows the subforums on the main page. I want users to be able to to see/select the sub-forum while hovering over the master forum.
