Drop Down Menu.

[rsteph]

I have a javascript drop down menu that I borrowed from a website. It utilizes a little .css to help with formatting. The menu works great, and on all 3 of the browsers I'm concerned about; but I am having one problem.

The menu, as designed, is a 1-tier menu (or is it 2-tier). It has the horizontal menu bar, along with the drop downs... but the drop downs aren't designed to propogate another menu (3rd teir). I was wondering if, but looking at the code I've got, anyone could see a *relatively* easy way to make this menu a three tier:

Here's the code:

And the .css:
 
#dropmenudiv{
position:absolute;
border:1px solid black;
border-bottom-width: 0;
font:normal 12px Verdana;
line-height:18px;

display: block;
text-indent: 3px;
border-bottom: 1px solid black;
padding: 1px 0;
text-decoration: none;
font-weight: bold;
}
 
#dropmenudiv a:hover{ /*hover background color*/
background-color: #7AD0E1;
}

Here's a link to the page with this menu on it:

And here's one with a different dropdown menu. (I actually like this menu, but it doesn't come out right in FireFox, and I haven't been able to get it fixed):

Anyone have any thoughts on this?

For an easy fix could use this menu instead:
