I have to believe this is possible. I've searched the ends of the earth, but not turned up anything that applies.
I use my sidebar for my main navigation. The navigation lists parent categories. When a parent is clicked, you arrive at the category page (via category.php in the Loop). I would like to display the subcategories that pertain to that category (as opposed to all of the subcategories)...and I only need to go one level deep.
Clicking the list of sub-sub-categories would then either take you to a page that lists more subcategories, or eventually the post itself. Kind of like cookie-crumb navigation in reverse, and displayed in the body content of the category landing page.
I've hit every external link that I could Google or find in this forum, followed every dead-end forum topic, and exhausted child_of, include, exclude, hierarchy and depth in the Loop in my category.php.
This has got to be possible. Many, many, many thanks to ANYONE who has an answer. This seems to be a topic issue that many people have.
