Custom Post Types Relationships (CPTR)

Custom Post Types Relationships (CPTR)

Details
View on WordPress

Most of the “related posts” plugins out there while they provide some kind of control on how to create related posts, they all rely on an algorithm
and the results are automatic. With CPTR you get total control as you can manually select the posts that you want to relate.
