Personalized Angular dropdown menu

Recently, I've started delving into angularJS and I'm eager to create dropdowns and tabs using both bootstrap and angular. Although there is a comprehensive angular bootstrap library available, I prefer not to use it in order to gain a deeper understanding of the underlying mechanisms. However, I've encountered some difficulties while attempting to develop the necessary dropdown functionality. The issue at hand is:

  1. I find that I have to click on the dropdown to close it if it's already open. Ideally, I would like to be able to close it by clicking or tapping anywhere outside of the dropdown.

I've created a pen showcasing my current markup and functionality: http://codepen.io/anon/pen/EBwlA

This happens to be my initial angular project; hence, if any aspect seems off-base or could be improved upon, please don't hesitate to provide feedback :)

Many thanks!

To enable collapsible functionality, simply add an ng-click event to each li or a tag with the following code:

 ng-click="toggleOpen($event)"

If you have a specific method in mind that you'd like to explore, feel free to let me know.

This approach involves using a service to facilitate coordination between collapsible elements:

app.service('collapsables',['$rootScope',function($rootScope){ return{ notify:function(event,payload){ $rootScope.$broadcast(event,payload); } } }]);

app.directive('collapsable',['collapsables',function(collapsables){
    return{
        restrict:'A',
        controller:function($scope){
            $scope.Toggle=function(){
                 $scope.expanded=!$scope.expanded;
                 collapsables.notify('toggled',{scid:$scope.$id,group:group});
             }
             $scope.$on('toggled',function($event,details){
                     var canClose=(!$scope.group || $scope.group==details.group || !details.group) && $scope.$id!=details.scid && $scope.expanded 
                     $scope.expanded=canClose.
              })
         }
}



}])

By attaching the collapsable directive to any element, you can facilitate communication between collapsibles and even group them for isolated behaviors. It's important to note that this directive doesn't create a new scope but enhances the existing one to include behavior. However, if multiple instances exist within the same controller, consider implementing a variant using isolated scopes for better organization while maintaining the core concept.
