Department page, with top navigation showing
I never really liked the functionality of the top menus for the old site, honestly. They were the ol' pop out navigation that were all the rage back in the early 2000's, but a lot of users had issues with them collapsing because your cursor went 1px too far out of bounds and you were technically no longer hovering over the menu.
Department page, with side navigation showing
Not a whole lot to say that wasn't said in the last two... This one just shows the side navigation menu expanded. It worked a lot like the top one (multiple pop outs), and essentially had the same issues.
