Update Google Forms field based on dynamic data from a Google Sheets spreadsheet
问题 In a Google Form we have a pull down selection list. The list of items may change from minute to minute. The master copy of the data is in a column in a google docs spreadsheet. When a user accesses the form, we want them to see the latest copy of the pull down list as is current in the spreadsheet. I don't see an obvious way to do this with triggers. onOpen, for example, only triggers for administrators of the form, not users. Is there a way I can keep this form up-to-date automatically?
