ActiveAdmin menu customization - second row

I would like to add a horizontal bar across the page just below the menu. It could be the bottom part of the menu, the top part of the content below the menu (title bar I think), or something different. I have found how to add or reorder links in the menu, but I need this bar to be a different color as well as have different items in it.


eta: Best I have so far is putting a div inside an element below and then using css absolute position and moving it up to just below the menu bar.
