I found this post, but it was never answered. I'm looking for the same thing, haven't been able to find a solution so far.
My problem is that I can't find a way to list subcategories unique to each post on a category archive page. My markup is currently this:
<article <?php post_class( 'grid_item' ); ?>> <div class="grid_item--inner"> <?php the_post_thumbnail(); ?> <header> <a class="cat_card--link" href="<?php the_permalink(); ?>"> <h2 class="cat_card--title"><?php the_title(); ?></h2> <?php get_template_part('templates/entry-meta'); ?> </a> </header> <div class="cat_card--cats"> <?php wp_list_categories('title_li=&style=none'); ?> </div> </div> </article>
This of course will list all subcategories of the current page's category. Looking through the WP codex documentation, I haven't been able to find a way to list only the applicable subcategories of each post. Is this possible? If so, how do I achieve this?
EDIT: To clarify, I'm interested in listing each subcategory like so:
Parent Category: "Video" - Post 1: Subcategory "Comedy" - Post 2: Subcategory "Action" - Post 3: Subcategories "Comedy, Action"
Where each post only lists the subcategories it uses.
