Better to use jQuery plugin like Superfish
http://users.tpg.com.au/j_birch/plugins/superfish/
//link to the CSS files for this menu type
<link rel="stylesheet" media="screen" href="superfish.css">
// link to the JavaScript files (hoverIntent is optional)
// if you use hoverIntent, use the updated r7 version (see FAQ)
<script src="hoverIntent.js"></script>
<script src="superfish.js"></script>
// initialise Superfish
<script>
jQuery(document).ready(function(){
jQuery('#menu ul').superfish();
});
</script>

Well, first add your submenu in the markup, for example:
<li>Services
<ul>
<li> sub menu item 1 </li>
<li> sub menu item 2 </li>
</ul>
</li>
....
Position your list items:
#menu li{
position: relative;
}
Style your sub menu:
#menu ul ul{
position:absolute;
left: 0;
top: 100px; /* height of the parent list item */
display: none; /* hide it */
}
#menu li:hover > ul{ /* show it when mouse is over the parent list item */
display:block;
}
