I currently have a mortgage website that uses a very complicated cascading drop down menu at the top of the page for navigation. It seems as though it does not work in browsers older than ie 6.0. It also works in Monzilla Firefox 1.05.06.
What I want to do is make it so that if someone comes from a browser other than one of those 2, that it disables the java drop down menu. When java is off surfers can still navigate the site because there are image links where the drop down menu is.
