I've been trying to get the following working for a couple of hours:
I have a views block, it displays a single content type. The content type has a taxonomy field. The taxonomy items are structured as this:
- option A - option B - option C - - option C1 - - option C2 - - option C3 - option D
I use the values to categorize the content of the nodes. Each node has a single taxonomy value and displays the view block itself.
I want the view to display all nodes of the same taxonomy (this is no problem for A, B and D). But for content tagged as C1, C2 and C3 I want to show all content within the parent taxonomy, "option c".
I have tinkered with depth and parent fields for relations/contextual filters without success... don't really know what to try next and I can't find and decent resources with similar examples that solves my problem. I would prefer to solve it within the views UI if possible.
