Is it possible to use limitTo filter on a ngRepeat directive which is repeating the properties of an Object and not items in an Array.

    limitTo works only for strings and arrays, for object use own filter for example:

    myApp.filter('myLimitTo', [function(){
        return function(obj, limit){
            var keys = Object.keys(obj);
            if(keys.length < 1){
                return [];
            }
    
            var ret = new Object,
            count = 0;
            angular.forEach(keys, function(key, arrayIndex){
                if(count >= limit){
                    return false;
                }
                ret[key] = obj[key];
                count++;
            });
            return ret;
        };
    }]);
