Angular: Showing only checked items in a checkbox list

Is it possible to show only a list of checked items in a checkbox list?

What I want to do is select a few items on a checked list and when I press "Show only checked items", I want to toggle between showing only the checked items in the checkbox list and showing the entire list with the checked items.

I searched angular's site but wasn't able to find a solution to it.

<div ng-controller="DemoCtrl">
  <label ng-repeat="role in roles">
    <input type="checkbox" checklist-model="user.roles" checklist-value="role.id"> 
  </label>
  <br>
  <button ng-click="checkAll()">check all</button>
  <button ng-click="uncheckAll()">uncheck all</button>
  <button ng-click="checkFirst()">check first</button>
   <button ng-click="checkFirst()">Show only Checked</button>
  <br><br>
  user.roles 
</div>

Javascript:

angular.module("DemoApp", ["checklist-model"])
.controller('DemoCtrl', function($scope) {
$scope.roles = [
    {id: 1, text: 'guest'},
    {id: 2, text: 'user'},
    {id: 3, text: 'customer'},
    {id: 4, text: 'admin'}
  ];
  $scope.user = {
    roles: [2, 4]
  };
  $scope.checkAll = function() {
    $scope.user.roles = $scope.roles.map(function(item) { return item.id; });
  };
  $scope.uncheckAll = function() {
    $scope.user.roles = [];
  };
  $scope.checkFirst = function() {
    $scope.user.roles.splice(0, $scope.user.roles.length); 
    $scope.user.roles.push(1);
  };

});
