I use QGis 3.0, created several layers, each with multiple attributes.
I want to display only objects which have f.e. "123456789" as value in a specific attribute to print it and repeat with the next value. It shouldn't just select the items but make everything else invisible. I don't want to filter every singly layer. A filter which applies to every layer would be perfect since the attribute has the same name and value in every layer for the same order number.
The list might make thing a bit more clear:
The upper layer group "Trasseninhalte" are cables and pipes and connections.
The lower side "Trassenobjeckte und APL's" shows burrows to be made or already existing, usable pipes. "Knotenpunkte", "APL" are just connection points.
