Is it possible to scroll to the top of the page when the "next" or "back" button is clicked?

Now we have got another problem: Is it possible to scroll to the top of the page when the "next" or "back" button is clicked? In this case, the user will be less irritated.

Furthermore, is there a way to make the iframe full responsive? Actually we are working with a fixed height, which makes the form very inflexible.

Thanks a lot for your help.

You can try using the full source code embed method:

 Note that with this method you will need to embed your form again each time you change your form.
