Hi Joachim,
no, unfortunately not.
The problem appears for taxomony archive pages that are children of the same parent. So, say, I set up a sidebar for Category Aa, Ab and Ac and define different widgets for each. Then on the frontend it shows the content for Aa, Ab and Ac on the taxomony archive pages of Aa, Ab and Ac and even Ad, Ae etc. and the children of these. That’s not what I want.
I thought I could define an individual sidebar for Aa, Ab, Ac and so on that only shows the content I put into the widget of that sidebar. Isn’t this possible?
Kindly, Andrea
