Show all terms that are children of term with argument tid I need a view that shows all terms that are children of the argument tid.

term 1
-term 2
-term 3
term 4
-term 5


view/4 should return term 5

I must be missing something fundamental because no matter how I mess with contextual filters and relationships I never come close to actually filtering my results by the context.
If you add a contextual filter for taxonomy term with depth modifier, it should work, e.g terms/1/1
