I suggest you to add this CSS to your Additional CSS List, in your style (AdminCp --> Styles & Templates --> Edit --> Add. CSS List):

.skin0{
position:absolute;
width:165px;
border:2px solid black;
background-color:menu;
font-family:Verdana;
line-height:20px;
cursor:default;
font-size:14px;
z-index:100;
visibility:hidden;
}

.menuitems{
padding-left:10px;
padding-right:10px;
}

Then, you can try to add this code..

<div id="ie5menu" class="skin0" onMouseover="highlightie5(event)" onMouseout="lowlightie5(event)" onClick="jumptoie5(event)" display:none>
<div class="menuitems" url="http://dynamicdrive.com">Dynamicdrive.com</div>
<div class="menuitems" url="http://dynamicdrive.com/new.htm" target="newwin">What's New?</div>
<div class="menuitems" url="http://dynamicdrive.com/hot.htm">What's Hot?</div>
<div class="menuitems" url="http://wsabstract.com/cgi-bin/Ultimate.cgi">Message Forum</div>
<div class="menuitems" url="http://dynamicdrive.com/faqs.htm">FAQs</div>
<div class="menuitems" url="http://dynamicdrive.com/submitscript.htm">Submit</div>
<hr>
<div class="menuitems" url="mailto:dynamicdrive@yahoo.com">Email Us</div>
</div>

<script language="JavaScript1.2">

</script>

In your headinclude template. It should work.
