The subterm overview template is the second most common standard template and is used on most terms that have additional terms nestled underneath them (aka “subterms”). This template does not have a zone to display “Posts,” but rather takes the Overviews of the terms below it. If you tag a post here, it will not display.
Here is the Overview of the first subterm. When you click on the title or the “read more,” you will be directed to the subterm itself, just as you would if you clicked on Subterm #1 in the left hand navigation menu.
