I have created a solution to fill a process document. The following fields must be filled Part before Resin before and Part after Resin after Since there is a fixed relation between part and resin, I would like to connect the part with the resin for typing in. I have a single select field for the part and the same for the resin. I'd like to choose only the part, and get, either an auto-fill for the resin or a fltered list of resins. The idea is, to prevent choosing the wrong material for the parts. I tried to find something in the list below or a tutorial, but without success. Thanks, and kind regards,
