The carryForwardPlusNA function moves non-carryforward choices to the bottom of the choice list. This allows for 'Other' or 'None of these' choices to be added to the list of carry forward selected choices while retaining the randomized order from the initial question.

To make the function available to all questions in the survey, copy the function to the Survey Header inside a script tag: Add the carryForwardPlusNA function to the survey header to make it available to any question in the survey. Go to Look & Feel → General → Header edit → and paste the provided carryForwardNA function JS:

<script>/*Paste carryForwardPlusNA function JS here*/</script>

Alternatively, paste the carryForwardPlusNA function JS into a question's JS outside the existing Qualtrics functions to make it available to questions on the page.
