I have in angular nested object like this. is there way how to filter it for nested property

<li ng-repeat="shop in shops | filter:search">
search.locations.city_id = 22

I'm showing only parent element but want to filter by both of it, like:

search = 
  category_id: 2
  locations:
    city_id: 368

[
 name: "xxx"
 category_id: 1
 locations: [
   city_id: 368
   region_id: 4
  ,
   city_id: 368
   region_id: 4
  ,
   city_id: 368
   region_id: 4
  ]
,
 name: "xxx"
 category_id: 2
 locations: [
   city_id: 30
   region_id: 4
  ,
   city_id: 22
   region_id: 2
  ]
]

Yes, you can, if I understood your example properly.

Depending on the size of your collection it may be better to compute the collection you iterate over in ng-repeat so that the filter isn't doing it constantly as the model changes.

Basically you do something like this, if I understood you correctly:

$scope.search = function (shop) {

    if ($scope.selectedCityId === undefined || $scope.selectedCityId.length === 0) {
        return true;
    }

    var found = false;
    angular.forEach(shop.locations, function (location) {          
        if (location.city_id === parseInt($scope.selectedCityId)) {
            found = true;
        }
    });

    return found;
};
