嘿伙计们，我遇到了IE7的问题，我的菜单总是落在它所在的div后面。

这里有太多代码：）
通常，当涉及下拉菜单时，我使用Chrome Menu。这真的很好，为我节省了很多时间。
<div class="chromestyle" id="chromemenu">
<ul>
<li><a href="http://www.dynamicdrive.com">Home</a></li>
<li><a href="#" rel="dropmenu1">Resources</a></li>
<li><a href="#" rel="dropmenu2">News</a></li>
</ul>
</div>
<!--1st drop down menu -->
<div id="dropmenu1" class="dropmenudiv">
<a href="http://www.dynamicdrive.com/">Dynamic Drive</a>
<a href="http://www.cssdrive.com">CSS Drive</a>
<a href="http://www.javascriptkit.com">JavaScript Kit</a>
</div>
<!--2nd drop down menu -->
<div id="dropmenu2" class="dropmenudiv" style="width: 150px;">
<a href="http://www.cnn.com/">CNN</a>
<a href="http://www.msnbc.com">MSNBC</a>
<a href="http://news.bbc.co.uk">BBC News</a>
</div>
<script type="text/javascript">
cssdropdown.startchrome("chromemenu")
</script>

在制作这些类型的东西时，我经常使用一些固定的CSS template。
在您的情况下，您可能会发现this site有帮助。它建议IE的代码片段（显然不适合您的代码）。
<!--[if lt IE 7]>
<style type="text/css" media="screen">
#menuh{float:none;}
body{behavior:url(csshover.htc); font-size:100%;}
#menuh ul li{float:left; width: 100%;}
#menuh a{height:1%;font:bold 0.7em/1.4em arial, sans-serif;}
</style>
