I would love to assist you. =D
The first thing you'll need to do is find this...
HTML Code:
$vbphrase[mark_forums_read]</a></td>
Add this below it...
HTML Code:
<td id="variable" class="vbmenu_control"><a href="#variable">Variable</a> <script type="text/javascript"> vbmenu_register("variable"); </script></td>
Change
variable to whatever you want. They are case-sensative and I would not suggest using spaces for the ones between quotations.
Now you'll need to add the information for the drop-down part. In the navbar, find...
HTML Code:
<!-- / NAVBAR POPUP MENUS -->
and add this above it...
HTML Code:
<!-- custom menu -->
<div class="vbmenu_popup" id="variable_menu" style="display:none">
<table cellpadding="4" cellspacing="1" border="0">
<tr><td class="thead">Variable</td></tr>
<tr><td class="vbmenu_option"><a href="index.php?">LINK</a></td></tr>
<tr><td class="vbmenu_option"><a href="index.php?">LINK</a></td></tr>
</table>
</div>
<!-- / custom menu -->
Change the urls, LINKs, and Variable to match your liking.
