Hi Roy,
The templates are customizable, which means you can edit the template and
put there anything you need.
To get what you want you can replace line #110 of the
Expandable/Collapsible template file with this:
<a href="<!--#echoe var='relurl'-->"><!--#echo var="fullname" -->
(<!--#echo var="size" -->)</a></li>
Hope this helps,
Paul.
