That’s a great question. Thanks for reaching out. Action Sheets are not a dynamic element inside Dropsource so they cannot incorporate dynamic data. Action Sheets choice settings are indeed limited to only static Strings. This would be a spot where a custom dynamic solution could be coded and added to your app outside of Dropsource in the source code as it’s a current limitation in the Dropsource platform. it wouldn’t be very typical situation to make an Action Sheet dynamic in its offerings since you have knowledge of the data represented on the page beforehand and can institute a set value inherently.
I wouldn’t recommend the dynamic code addition in this situation however. I would recommend thinking about the data coming in prior to the action sheet showing up and setting a design standard in the app to allow you to know what options for filtering the Action sheet should provide though.
