Joel, I'm currently implementing your superfish JS function into a vertical navigation structure and so far, it's worked out great. There is, however, an issue with IE6 as it doesn't open the menu at all and for the life of me I cannot figure out why. I'm using JQuery 1.1.4 and Superfish 1.3 with the bgIframe plugin.
I've posted the site as it stands now out at the following web URL. Any help in fixing this is very much appreciated. http://216.120.230.80/~rieekan/home.html - George
