   Hi guys,

   Here is the situation. I have a site composed of pages and posts and different categories.
   I want to show in the sidebar, a custom menu based on the new menu from WP 3.0.

   I am already showing it on all child pages of any given page (is_tree) but I would also want to be able to show it on categories that are added in the custom menu.

   <?php
   	// A second sidebar for widgets, just because.
   	if ( is_tree('8') ) : if ( is_active_sidebar( 'projects' ) ) : ?>

   So what I'm looking for is a function that will return true or false, if it is a subcategory of a defined category. Something that will end up like this:

   <?php
   	// A second sidebar for widgets, just because.
   	if ( is_tree('8') || is_subcategory('7') ) : if ( is_active_sidebar( 'projects' ) ) : ?>

   Thanks

   Found the function: IS_SUBCATEGORY_OR_SUB

   // If is category or subcategory of $cat_id
   if (!function_exists('is_category_or_sub')) {
   	function is_category_or_sub($cat_id = 0) {
   	    foreach (get_the_category() as $cat) {
   	    	if ($cat_id == $cat->cat_ID || cat_is_ancestor_of($cat_id, $cat)) return true;
   	    }
   	    return false;
   	}
   }
