   I need to be able to display multiple child categories with links, like this (with free text prepended).

   Color: Red
   Shape: Circle
   Size: Large

   I found a great solution at http://wordpress.org/support/topic/how-to-display-the-child-category-of-a-specific-parent-category?replies=18, which I've tweaked to include the prepended text.

   <?php
   foreach((get_the_category()) as $childcat) {
   if (cat_is_ancestor_of(10, $childcat)) {
   echo 'Color: ' . '<a href="'.get_category_link($childcat->cat_ID).'">';
   echo $childcat->cat_name . '</a>';
   }}
   ?>

   However, I'm unable to get multiple iterations to work. I tried adding and endif; to each with no joy.

   How can I get this to work?

   Thanks.

   Diana

   Ah, I just had to nest them properly:

   <span class="cat-links">
   	<?php
   	foreach((get_the_category()) as $childcat) {
   	if (cat_is_ancestor_of(3, $childcat)) {
   	echo 'Color: '. '<a href="'.get_category_link($childcat->cat_ID).'">';
    echo $childcat->cat_name . '</a>';
   	}
   	if (cat_is_ancestor_of(10, $childcat)) {
   	echo 'Shape: '. '<a href="'.get_category_link($childcat->cat_ID).'">';
    echo $childcat->cat_name . '</a>';
   	}
   	}
   	?>
   </span>
   <?php endif; // End if categories ?>

   Last step, need them displayed in parent ID order. By default, content is displayed by Child alpha order. Changed get_the_category() to get_the_category('orderby=ID&order=ASC'). No joy.

   Any ideas?
