Dynamic menus with cool effects!

[FONT=verdana, arial, helvetica][SIZE=2]Hi,
I am having trouble working out exactly what is happening behind the scenes when dynamic menus/ submenus get displayed with some effect.

I am able to read in an xml file, create a menu, and display submenus with the use of a rollover event. The submenus appear immediately, all at once. However i would like the submenu items to appear with some effect.

For example,
[COLOR=orange]http://www.vw.com/models_overview/index.html[/COLOR]

The “models” button in the top left corner has the features i want.

  1. With a mouse over i want a menu to appear. The first submenu item to be appear is the last on the list.

  2. when the mouse drifts off the list, the submenu retracts in the same order it appeared.

How is this done? I do not want/expect any script. If anyone can explain the steps involved in creating such a menu i’d love it!

I’ve been messing around with this for days but i really dont understand what the concepts are

How should i be thinking about doing this?
Do you use masks? or is there something a little more sophisticated?

thanks[/SIZE][/FONT]
