Hi,

I'm new here. I was experimenting with horizontal dropdown menu using only CSS. The following is my code so far:

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>

<head><title>test</title>

<style type="text/css">
#menu {
	font-family: Verdana, Arial, Helvetica, sans-serif;
	width: 800px;
	height: 30px;
	background-color: #FF9C3C;
}

#menu ul {
	margin: 0px;
	padding: 0px;
	list-style: none;
}

#menu ul li {
	float: left;
	width: 108px;
	height: 30px;
	line-height: 30px;
}

#menu ul li a {
	font-size: 12px;
	text-decoration: none;
	display: block;
	text-align: center;
}

#menu ul ul,
#menu ul li:hover ul ul {
	display: none;
}

#menu ul li:hover ul,
#menu ul ul li:hover ul {
	display: block;
}

#menu li {
	position: relative;
}

#menu ul ul {
	position: absolute;
	top: 100%;
	left: 0%;
	background-color: #DDDDDD;
	border-width: 1px;
	border-style: solid;
}

#menu ul ul ul {
	position: absolute;
	top: 5%;
	left: 95%;
	background-color: #FFFFFF;
	border-width: 1px;
	border-style: solid;
}

</style>


</head>

<body>

<div id="menu">
  <ul>
    <li><a href="test">test</a>
	  <ul>
	    <li><a href="test">gteata</a></li>
		<li><a href="test">gtegerata</a>
		  <ul>
		    <li><a href="test">gteata</a></li>
			<li><a href="test">gteata</a></li>
		  </ul>
		  </li>
	  </ul>
	</li>




	<li><a href="test">me</a>
	  <ul>
	    <li><a href="test">gteata</a></li>
		<li><a href="test">gtegerata</a>
		  <ul>
		    <li><a href="test">gteata</a></li>
			<li><a href="test">gteata</a></li>
		  </ul>
		</li>
	  </ul>
	</li>
  </ul>
</div>

</body>
</html>
The code above works for Opera, Firefox and Safari. However, when I tested it in IE 7, a weird thing happens. You can play around with the menu, and occasionally, when you hover any one of the main options, 2 levels of menu appear at the same time instead of 1.

Does this require any sort of hack to fix? Or am I missing something?

Thanks a lot for any help in advance.
