That is great, exactly what I needed. “Just One Category” plugin
I was using categories as a navigational query, and all the post from the subcategories would show up if I clicked on the parent. Now I can select each individually. Also, I am able to select multiple categories for the post, so it will show up in each of the sub categories…if I prefer. No problems with the recent posts…WP-2.92, Before I had been using the plugin “page links to” to navigate to certain areas or external areas.
