Auto complete widget: Ability to allow the user only fill whatever in the list

Yes, i am using AutoFill widget, the problem is people still able to answer not only based on Autofill list.

Can i make so they could only fill whatever in the autofill list?

Unfortunately, it is not possible to restrict the users to select only the list of items from the widget. Let me forward this thread to our backend team as a feature request for evaluation. Please note that we cannot provide any ETA at this moment. However, if there is any news you'll be updated here on this thread.

Thanks!
