   Hey guys. I'm using WP as a CMS for a site and I'm using categories and subcategories for the basic structure of the site.

   IE:
   About Us (main category)
   -Directions (sub cat)
   -Contact Us (sub cat)

   Groups (main category)
   -Men's group (sub cat)
   -Women's group (sub cat)
   -Teens (sub cat)

   My question is how do I get the list of subcategories to only appear under its parent? I did this with creating custom category template + custom sidebar file but that's way too much files.

   I also used this PHP code to do the same. The only problem is that this only shows the subcats in their parents, but once I click into a subcategory, the list of links disappear.

   <?php
   
   if (is_category()) {
   	$this_category = get_category($cat);
   	if (get_category_children($this_category->cat_ID) != "") {
   		wp_list_categories('orderby=order&show_count=0&title_li=
     &use_desc_for_title=0&hide_empty=0&child_of='.$this_category->cat_ID);
   	}
   } ?>

   I want to keep using this PHP file but how do I use it so that it shows the list of subcats even though I'm in one of the subcats?

   I hope that made sense.

   Okay I sort of got the answer.

   I have this code going:
   

   <?function get_parent_category() {
    global $wp_query;
    $category = $wp_query->get_queried_object();
    if ($category->category_parent) return $category->category_parent;
    else return $category->cat_ID;
   }?>
   
   <?php $id = get_parent_category();
   if ($id) {
   	echo "<ul>";
   	echo wp_list_categories("orderby=order&option_count=1&hierarchical=0&hide_empty=0&use_desc_for_title=0&child_of=".$id."&title_li=");
   	echo "</ul>";
   } else {
   	include(TEMPLATEPATH .'/sidebar-general.php');
   } ?>

   So basically I'm calling the id, and sticking the id after "child_of" and also making sure that it appears in the child categories.

   The only thing that bothers me is that it says "No Categories" whenever I go to a category without a subcat.

   How can I make it so that it doesn't show "No Categories" when no subcategories are present in that category?

   Any help here?

   Okay so since I'm terrible at PHP, I just went into wp-includes/category-template.php

   and changed the lines (around lines 254)

   if ( 'list' == $style ) //inserted "nocats"
   			$output .= '<li class="nocats">' . __("No categories") . '</li>';
   		else

   As you can see, I inserted class="nocats" after the first list tag opener so that I could use css to display: none; to hide it.

   Just a round about hack.
