I was recently working on converting a Design to Xhtml, CSS ..The design had a horizontal navigation with a secondary navigation..I set about to converting it and then I realized that I had never done a horizontal navigation with multiple levels before..So I set about searching the net on how to accomplish it. I wanted to incorporate jquery into it as well. I found a site that had the kinda effect that I wanted. So I explored how they did that. I found that it was pretty easy. So I set about writing an article on it.
