I try to make a post submit form (nestable) where the user can select a taxonomy term.
I want to fill the options via query loop. So far so good.
My Taxonomy is hierarchical so some of the terms are parent and have some child terms.
I expected that the select field will show the terms like this:
-Child1 of Parent1
-Child2 of Parent1
-Child1 of Parent4
-Child2 of Parent4
-Child3 of Parent4
-Child4 of Parent4
But I can’t get it work.
Has anyone the secret hint for me?
