I'm really stuck on this:
Is there some way I can make a widget (or hard-coded sidebar element) appear both in a specific category's sidebar AND in posts belonging to that category?
I never assign more than one category to a post, so at least that should not be any problem.
I can use Widget logic to make eg. a text widget appear in just one category, but then it won't show up in the posts (assigned to that category).
Some line of code I can use? Ideas?
Grateful for any hints!
