A Six-Level Cascading Image Menu

A cascading menu is a list of links that is invisible until you move your mouse over an existing link on a page. When your mouse is over the link, the cascading menu becomes visible, and you can scroll through the menu and click a new link.

Since menu systems within popular programs like Microsoft Word and Microsoft Internet Explorer use cascading menus, most people are familiar and comfortable with how they work. And because they're hidden until you mouse over them, cascading menus are a great way to display a lot of links without using up a lot of web page "real estate."
