 JavaScript is a 2-level combo box menu script. Organize and compact categories into link, all displayed using just one selection box. The navigation that requires absolutely no DHTML or Javascript experience. It is creates any cross-browser, popup or drop-down menu that works alike in all browsers supporting DHTML and in all platforms. The navigation DHTML/JavaScript menus are designed with a treelike approach. Users can tailor their menu by using the Properties Pane or by choosing a predefined appearance from the Style Gallery. The menu can be either vertical or horizontal, that can be movable, stay visible while scrolling, contain static or animated images, borders, colors, and much more. Once everything is set, you can use the insert-menu-into-Web-page command to add  menu in the Web page in a fast and easy manner without any code.
