I have been searching for a way to add all countries as a predefine, but I did not find an answer to my question in the existing documentation.
I wonder if it is possible to automatically add all countries as a predefine and in a Q&A have this displayed as a drop down menu. Or as a field that the user can type in themselves and then click the suggestion. E.g. If he starts typing “Fr”, that it shows “France”.
You can either use the Global Placeholders system or the spreadbases. But I think you will like the spreadbases better, because they indeed allow for such a dropdown with type-ahead functionality!
You can then add a list of desired countries through, for example, Excel (one column having the internal code such as “BE” / “FR” / etc., and other ones having the full names, potentially in different languages).
