I have built the following code that creates a simple collapsable menu, with a link (onmouseOver) but the problem i have is I would like this to be within a table so that when you place your mouse over the top link it displays the extra (hidden) links with new table rows.

<title>Navagation Link (onMouseover)</title>
<style type="text/css">
#menu {width: 140px;background: white;}
#menu div {display: none;}
#menu div a ,img {text-decoration: none;}
#menu div a:hover {text-transform: uppercase;}
<script type="text/javascript" language="javascript">
// Navagation with Link
function show(which) {
var m, els, el, i = 0;
if (document.getElementById) {
m = document.getElementById('menu');
els = m.getElementsByTagName('div');
while (el = els.item(i)) {
if (which == i)
el.style.display = (el.style.display != 'block') ? 'block' : 'none';
else el.style.display = "none";
onload = function() {
var Q = location.search.substring(1);
if (Q) {
var menu = Number(Q.split('=')[1]);
<div id="menu">

So to recap. I would like the whole thing in a table (5 rows - 1 col) 140px wide. with the head link in each row. When the mouse is placed over one of the head links the extra rows automatically appear below. Maybe with a different background color to highlight that these are sub menus.

Thanks for any help in advance!
