In the Tasks edit form this is this nice way to select one related module and record for the relationship (one= project, many=tasks). Tasks can be associated with several modules. I have a custom module (donations) that likewise can be associated to either donor organizations or contacts. For custom modules it looks like i would have to have a separate field for each possible parent relationship. I want to have a similar dynamic drop down that creates/edits the relationship. Is this possible?
See attached to where it appears on the task edit form.
