Can a behavior action be triggered by a dropdown selection?
i don’t think so if you literally mean AppSheet actions. What is your use case? If you are just trying to offer different value selections based on a prior drop-down selection this is possible with column expressions since you have access to the selected value via [_THISROW]..
@decpro350 You could trigger the action as “Event action” and then the dropdown usage could be possible… at least somehow. My sample case would be a situation where you choose the value from the dropdown and when you save the record, you trigger that Event action. If you set the correct target formula for your action, you can change the behavior.
I, too, would like to know what you’re trying to accomplish.
