I use the drop downs all over my site... including as my forumjump.
First create the drop down table and populate it. I've attached the code you'll want to change yourid to whatever you want to call this drop down.
PHP Code:
<div class="vbmenu_popup" id="yourid_menu" style="display:none">
<table cellpadding="4" cellspacing="1" border="0">
<tr>
<td class="thead">Title Here</td>
</tr>
<tr>
<td class="vbmenu_option"><span class="smallfont">Content Here</span></td>
</tr>
</table>
</div>
In your table where the drop down is going to live, create a cell like the one below, remember to change yourid to whatever you called the dropdown table above.
PHP Code:
<td class="vbmenu_control" id="yourid"><a href="#goto_yourid">Your Title</a></span> <script type="text/javascript"> vbmenu_register("yourid"); </script></td>
You'll have to use a span tag to set the font attributes as you cannot change the class tag from vbment_control.
Paste the table with the div tags below the </script> tag in your header and your in action.
