JS corner expression in ng-repeat

Question

I would like to know what is the most elegant and easiest way to implement this. I need to add a filter expression for ng-repeat that will filter 2 conditions from one property.

In this example, http://plnkr.co/edit/OMQxXvSjtuudMRGE4eZ8?p=preview

• If you enter A, a check box for A is displayed.
• check B - display for B.

But I want to show the indicated flags plus something with an empty condition. There is no condition for C, therefore:

• if you enter A, I want to display flags A and C,
• enter B, I want to display both flags B and C.

, :

app.filter('myfilter', function() {
   return function( items, condition) {
    var filtered = [];

    if(condition === undefined || condition === ''){
      return items;
    }

    angular.forEach(items, function(item) {          
       if(condition === item.condition ||  item.condition === ''){
         filtered.push(item);
       }
    });

    return filtered;
  };
});
