JQuery simply adds the cool effect to dropdown menus. Not too many people turn off JS, but for the ones that do, your menu would simply appear and not slide down. Try this out http://route19designs.com/DP-Menu/. Try it with JS turned on and try it with it turned off. as far as the multi level flyout, http://www.webdesignerwall.com/demo/css3-dropdown-menu/css-gradient-dropdown.html. I know I will get criticized for this, but I do not design for IE6 at all. Don't care really.
