Topic Tag: Views plugin

Problem:
The user would like to filter a custom post type by the taxonomy of a related(child) post type in a Toolset relationship.

Solution:
That's not possible out of the box. We cannot filter posts by taxonomies or custom fields from a related post type.

However, we can sync the taxonomies from the child post to the parent post and use it there. Check the code that the user was using to sync the taxonomies when a child post is submitted.
