I need a function that when I click on field A, this field should only execute the values from field B which have the relationship about the data model. Is there anywhere an example about something like that.
I think you will need to provide more details maybe with a few examples when should what happens. And for what reason might also be helpful then maybe there are other ways possible, too.
Whatever value you select in field A, filters the corresponding values in field B, provided of course, that the tables these fields belong to are connected, or they belong to the same table.
