Question types like comment questions & contact information questions have a question-level submit button. For example, see the "comment" button below:
If you've opted to include a submit button at the end of your survey, you may find you don't need the question-level submit buttons. Having multiple submit buttons can become tedious for participants. To solve this issue, you can hide the question-level submit buttons on the Page & Survey tab.
Scroll to the bottom of the Project Questions and Dynamic Content section and Toggle on the Show submit button on final step (formerly the End-of-Page submit button.)
Once you've enabled the submit button (indicated in green,) click More Submit Options. You'll see the option to Hide the question-level comment submit buttons. Toggle this on as well.
This will remove the question-level submit buttons across your survey, allowing participants to submit all survey responses with just 1 click!
