Please set the none option to appear as the last concept then add this script to your CBC:

    $('#[% QuestionName() %]_div .cbc_concept.concept_1').before($('#[% QuestionName() %]_div .cbc_concept.none_concept'));

function SSI_SetBestConcept(question, conceptIndex) {
    var conceptClass;
    if (conceptIndex) {
        conceptClass = '.concept_' + conceptIndex;
    else {
        conceptClass = '.concept_' + $('#[% QuestionName() %]_div .cbc_concept').length;

    var concept = question.find(conceptClass);
    if (concept.length) {
        if (concept.is('.worst')) {
        SSI_SetBestResponseDot(question, conceptIndex);

Test thoroughly.  Some changes may be necessary if using a best-worst or constant sum CBC.

Is there a way to add to this to make the none option like slightly shaded?
You want the background color of the none concept to be a light gray?
Yes light grey would work
Please try adding this CSS to your exercise:

.none_concept {
    background-color: lightgray;

"lightgray" can be replaced with any other CSS color name, or a hex code like "#EEEEEE".
