Matrix carousel multi select - how to set up exclusive option

Hi @EvaZw you can use custom validation to create a specific combination of conditions through which respondent can pass the questions.
NOTE: This can prove to be lengthy and complicated if you have large number of statements and scale points.

Thank you @TomG! The code works! I have applied it in a multi-choice carousel where the 9th column is exclusive. 

Qualtrics.SurveyEngine.addOnload(function() {
  /* carouselExclusive.js */
  /* Thomas Gibbons Consulting (qualtricswiki.tgibbons.com) */
  var q = jQuery(this.questionContainer);

  // Add 'exclusiveCB' class to checkboxes in column 9
  q.find(".CarouselAnswerButtonContainer").each(function() {
    var columnIndex = jQuery(this).index();
    if (columnIndex === 8) { // Column index is zero-based, so column 9 is index 8
      jQuery(this).find("[type=checkbox]").addClass("exclusiveCB");
    }
  });

  var cbs = q.find("[type=checkbox]"), 
      exCbs = cbs.filter(".exclusiveCB"), 
      notExCbs = cbs.not(exCbs);

  exCbs.click(function() { 
    if (this.checked) cbs.not(this).prop("checked", false); 
  });

  notExCbs.click(function() { 
    if (this.checked) exCbs.prop("checked", false); 
  });
});
