Here's an example page of my jQuery plug-in: "Slide box". With it, you can take any div and transform it into a top/bottom sliding panel. Try it now by clicking on "Ouvrir" at the top of this page.
Simply include the slidebox.js library to your page and enter this code in your page header.
$(document).ready(function(){
$("YOUR DIV").slideBox();
});
You need the slidebox.css file and slidebox.js.
If you want this whole page as an example load this slidebox.zip file.
And of course, you'll need the jquery library available at jQuery.
