I maintain and update websites at my place of work. I have to alter one of our pages to have a flyout menu instead of the convention html menu's. I understand that this can be done with javascript or dhtml. I don't really have a clue where to start to try to create a flyout menu.

The quintessential example of CSS menus is the "suckerfish dropdowns". Note that a "dropdown" is equivalent to a "flyout", I think.

If you do a web search for "suckerfish dropdowns", you'll find everything you need. If not, just post questions to this thread and we'll work it out.
