Actually, there are articles written by several authors. Those authors belong to a certain subject, and the subject belongs to a certain territory.
For example:
Subject 01
– Territory 01
—- Subject 01
—- Subject 02
——– Author 01
——– Author 02
– Territory 02
In the article, users should be able to click on the author name and see what Subject and what Territory it belongs.
Maybe there is a plugin for this?
Thank you in advance.
