How do I select parent or child when using terms query loop?

[digismith]

I may misunderstand, but I found a code-free - native bricks way to show only the children of the current term. My answer here:

Only show parent term from custom taxonomy

You can do this with the default Bricks query loop by setting the parent value to 0. [query-only-parents]

I have an archive template that does this - listing child terms above a post grid. Works for me.
