In the Views UI I set up the
Relationship "Taxonomy:Parent term" and then a
Field "Taxonomy: Term" with that relationship.
But the problem is that It displays the parent terms of all the vocabularies (I have several vocabularies). I also tried the
Field "Taxnomy:All terms" as it can limit the terms by vocabularies but it can't have the
Relationship "Taxonomy:Parent term"
Is there any way to display only the parent terms of one certain vocabulary for hierarchical taxonomy in a view field?
