CSS Dropdown menu for the header- With Categories!

[Get Em Fast]

I see the Div must have a height, in order for overflow to work.

div#dropMenu ul.level3 {max-height: 600 px; overflow: auto;}
div#dropMenu ul.level4 {max-height: 600 px; overflow: auto;}


I thought that this would work, but it does not.

Well, not only do you need the "max-height" that you have, but you also need "height". You also don't want the scroll to work both horizontally AND vertically, so you would want something like this:

div#dropMenu ul.level3 {height: 600px; max-height: 600px; overflow-y: scroll;}

BUT, the downside is, while this will work for level 3 dropdown, it will also cancel out level 4 from displaying at all.
