How can I allow users to select different language versions of a questionnaire?
Simply create new card or question with the “document language” button like in the screenshot below.
I usually prefer to put this card/question somewhere at the top of the questionnaire so that users can immediately start drafting in their language of choice but this depends on your personal preference.
You can also take a look at the “options” menu at the left-hand side of the screen. In this menu, you can set out different options for how language is interacted with in the questionnaire.
