CSShiarchMenu
This script will generate a nice hiarchical dropdown menu in DHTML. This script is tested under firefox, mozilla, opera and msie 6. All layout stuff can be configured in the CSS stylesheet. I've build this script only for my own site. But to make your life easy I've made it open source ;) This menu can do vertical suff also, it's configurable in this version. You may use the script any way you like, but a link back to me would be nice ;) Have fun.
