Below is an example of the code I used to create a dropdown menu in the postbit_legacy template. The code mimics the code used in the forum menu for creating a dropdown menu, only this one does not use links but rather static text.
Instructions:
Replace all Instances of $post['field#'] to list the proper field name of each custom profile field you wish to include and follow the format below to add additional fields. Only 3 fields were shown in the code to reduce the length of it. When adding a new field you should add it to the first vB conditional as well as the code for listing it. The conditional for displaying each field is optional and by some may be considered excessive, this is entirely up to you! You also do not have to use inline styling as I have but this was thrown together quickly to get something that works.
HTML Code:
<!-- post specs_menu -->
<vb:if condition="$post['field#'] OR $post['field#'] OR $post['field#']">
<div class="userinfo_extra">
<ul>
<li class="popupmenu">
<a href="javascript://" class="popupctrl" accesskey="6">Computer Specs</a>
<ul class="popupbody popuphover">
<vb:if condition="$post['field#']">
<li style="width:300px;color:#808080"><span style="font-weight:bold;color:#EEE;">Case:</span> {vb:raw post.field#}</li>
</vb:if>
<vb:if condition="$post['field#']">
<li style="width:300px;color:#808080"><span style="font-weight:bold;color:#EEE;">Motherboard:</span> {vb:raw post.field#}</li>
</vb:if>
<vb:if condition="$post['field#']">
<li style="width:300px;color:#808080"><span style="font-weight:bold;color:#EEE;">Processor:</span> {vb:raw post.field#}</li>
</vb:if>
</ul>
</li>
</ul>
</div>
</vb:if>
<!-- / post specs_menu -->
I hope this helps and that I have posted this code in the right section :P
