Hi @percezione,
Have you tried using the autocomplete in the appearance? Tryout the steps as mentioned and this should help sort out your problem:
- If you are designing the form in XLSForm, you simply need to type autocomplete in the appearance column against the question.
- If you are using the KoBoToolbox Formbuilder Interface, in the question, click to the setting button > Appearance (Advanced): > other > (type) autocomplete
- Click to SAVE and you are done.
