I have two tables: One, where I digitize water pipes (A) and a second one with pipe-types(B, not mappable). The pipe-types layer contains several columns like
diameter_outside etc. When I digitize a pipe in my layer, I just want to select via dropdown menu one of the types which are included in the pipe-types layer. All the other fields should then be automatically filled with the corresponding information.
So far, I only get my drop-down menu via layer properties -> attribute forms -> widget type "value map" and selecting the type-layer here. How can I reach the autofill function for the other fields?
