What I'd like to do is have a hierarchical category list in my sidebar, with:
Do not display sub-categories if the number of posts = zero
Display parent categories if the number of posts = zero only if a child category number of posts > zero.
Does that makes sense?
Here's what I'm using:
<?php list_cats(0, '', 'name', 'asc', '', 1, 0, 1, 0, 1, 1, 0,'','','RSS','','', 1) ?>
