flyout menu examples?

[Faithless]

Is it possible to make a menu that will drop the child elements below when you hover on the parent and then when you hover on the child it flys out?Something like this but obviously goes down on hover of parent.http://www.vision.to/simple-css-one-level-flyout-menu.phpedit: could you show me an example of a menu based on my description. I would like to learn how to do this. Thanks
