webfeuerflo if you filter for instance for "mathematik" and then sort for "Schulstufen", why is "class-ninjas" the last item?
Firstly, you set to filter by tag, so when select 'Mathematik' in the filter, it will show all items having this tag
And, it will list item by the ID of item in Articles list in backend.
And when you select to filter by range 'SCHULSTUFEN', for example, I select '5', it will filter the value from 5 to 13
All items match this condition will display, it not depend on the which value has '5' value to display first.
I hope this makes sense.
