If a post has been filed under multiple categories, the default is to list each category at the end of each entry.
However I want to display only one category at the end of an entry. To give an example, one of the Parent categories is "Author", and its child categories are "author-1", "author-2", "author-3" etc. I want only the child category "author-x" to be displayed.
There are other categories that I also have the post filed under(Book Title, Publisher etc), but I want to omit these for now. Any ideas?
I have spent a long time googling and cannot find any answers.
Thank you for any replies.
