DHTML/JS navigation that's compatible w/all browsers

This is a very simple navigation system with one "Main Menu" top navigation layer and one "Submenu" layer. The requirements are: * Code snippets of your work, indicating how you code, efficiency etc? any script will do. * That this MUST be 100% compatible with IE 5+ and Netscape Communicator 4+. * I will also need cleanly commented codes that allow me to add and edit categories in the Main Menu and Submenu. * I WILL NOT ACCEPT pre-configured scripts that you can edit and send me. * I need the Main Heading to be images that mouse over to another images and editable text in the Sub Menus. The site will look very similar to this menu: http://www.proacttechnologies.com. I need this to be much faster in terms of load time. Unlike the one currently made by those guys? it should be more like this: [login to view URL] Regards ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform DHTML/JS, any other creative means you might have to make the scipt above work great.! very open to new scripting languages and practices.
