How do I allow users filling in my form to add the form again and fill in

Hi. 

I want to do something similar to the Widget "Configurable list"  where there is 6 questions a person need to answer and the if they click on the + sign it adds the 6 questions again to fill in. 

The problem I have is I want to questions to be below each other and not next to each other as in that Widget. How can I do this?

It is possible to position fields to be below each other inside of Configurable list but only with CSS. We can help you with the CSS code, but I would suggest you to finish your form first and then provide us ID of the form.

Other solution would be to use regular fields and duplicate them and use conditional logic to show new fields.
