You have an error in your source code.
Your LI tag inside the UL are not closed.
The solution to your problem:
<li style = "position: absolute; top:0; left:0; width:200px; height: 20px;"></li>
(please close your LI tags!)
width and height are whatever you want them to be
Of course, you can make the CSS external, but you get the idea
In order for this to work, make sure the UL container has "relative" positioning:
<ul style = "position:relative">
