Menu at different level visible simultaneously in CSS - html

Question

I have this CSS:
Here is the example: Here is the example: http://jsfiddle.net/GrkkW/1/
#menu{
width:952px;
height:36px;
line-height:36px;
padding:0 0 0 32px;
background-image:url(/images/menu_bg.gif);
background-position:top left;
background-repeat:repeat-x;
position:relative;
z-index:100;
float:left;
}
#menu li{
display:inline;
list-style-type:none;
float:left;
position:relative;
z-index:100;
}
#menu li a{
font-family:Tahoma;
font-size:11px;
color:black;
text-decoration:none;
margin:0 15px;
padding:3px 8px;
display: block;
}
#menu li > ul
{
display: none;
line-height: 20px;
height: 20px;
}
#menu li:hover ul{
display: block;
position:absolute;
margin: -5px ;
}
#menu li:hover li{
float: none; }
#menu li:hover li a{
background-color: #0C325F;
border-bottom: 1px solid #0C325F;
color: #D2DEEC; }
#menu li li a:hover {
background-color: #8db3ff; }
and HTML is this:
<ul id="menu">
<li>Home</li>
<li>Item1
<ul>
<li>SubItem1
<ul>
<li>Sub1</li>
<li>Sub2</li>
</ul>
</li>
<li>SubItem2
<ul>
<li>Sub1</li>
<li>Sub2</li>
</ul>
</li>
</ul>
</li>
<li>Item2</li>
I'm using this to display a menu and submenu. What I want to achieve is that when an option from the second level is clicked then its submenu is visible. However currently when I click on menu, submenu at level 1 and level 2 are displayed simultaneously.
I'm wondering if somebody can help me with this and give some advise of the modifications I need to add to the CSS to achieve this?
