Adding records to a linked table based on a conditional field of the present filtered set.
Per post title, I have a need to have a drop-down object that contains records of a filtered table and related to the current open record. What I have in mind for appearance and action, would be like a drop-down value list but ancually be selected fields in filtered records of a related table and anchored to the current record in List View. I don't care if this drop down lays over subsequent records of the working view or <temporarily> pushes the subsequent records down. I will need to add records to this drop-down portal (window) before committing the present open record.
A conditionally created portal may work, but I can't find a way to do this.
Alternatively, creating a <temporary> new window with a filtered layout and based on the related table would probably work. Additionally this new window would idlealy be anchored to the initial window so it appears as a drop-down. I haven't tried this yet, but I expect I could get it to initially appear in the right spot but I don't have high confidendce that I could get it to move with the window that created it.
Does any one have any suggestions? Please.
