    I suggest you those functions :

      $scope.open = function (index) {
        $scope.groups[index].isOpen = !$scope.groups[index].isOpen;
        $scope.closeOthers(index);
      }
    
      $scope.closeOthers = function (index) {
        for(var i = 0; i  < $scope.groups.length; i++) {
           if (i !== index)
            $scope.groups[i].isOpen = false;
        }
      }
    

    open is fired when clicking on a parent, closeOthers is called in open. I init a visible boolean to parents. Each time user clicks on a parent, it set visible to true, and others to false.

    <div ng-controller="AccordionDemoCtrl">
        <div>
          <div  ng-repeat="group in groups track by $index">
            <div class="parents"  ng-click="open($index)"><i ng-class="{'glyphicon-minus': group.isOpen, 'glyphicon-plus': !group.isOpen}"></i> {{ group.title }}        
            </div>
            {{ group.content }}
            <ul class="childs" ng-show="group.isOpen">
              <li ng-repeat="item in group.list">
                <span ng-bind-html="item"></span>
              </li>
            </ul>        
          </div>
        </div>
      </div>
