mygosuMenu is a set of simple DHTML menus. All menus are lightweight, fast, free, search engine friendly and compatible with most browsers. They are simple because each of them has been separated into three distinct abstraction layers: Engine layer - javascript code (menu.js). Presentation layer - cascading style sheets (menu.css). Structural layer - html (menu.html). Currently there are available: XulMenu - windows like menu with unlimited nesting. Drop down menu with unlimited nesting. Click-show-hide menu. Tree menu. 1-level drop down menu
