<label class="concentration-label3" ng-repeat="subject in subjects">
  <input type="checkbox" name="concentrations" class="concentration-label3__input js-concentration-value" value="" data-mixpanel-subject="Design">
  <span class="concentration-label3__title" for="conc1">
    {{subject}}
    <span class="concentration-label3__title__checkmark4"></span>
  </span>
</label>
