To show the subcategories for a given category on it’s category page in the sidebar, but somehow the code for this wasn’t readily available. Basically you need to check whether there are any children, and if there are, list the categories with the current category as a parent or grandparent. The following code does just that:

if (is_category()) {
  $this_category = get_category($cat);
  if (get_category_children($this_category->cat_ID) != "") {
    echo "<h1>Subcategories</h1>";
    echo "<ul>";
    wp_list_categories('orderby=id&show_count=0&title_li=
&use_desc_for_title=1&child_of='.$this_category->cat_ID);
    echo "</ul>";
  }
}

Have fun with it!   Thanks to Yoast
