'ng-repeat' How to get the `unique` values

Using an array, I am trying to filter and show the unique information in the list. For that I use the angular inbuild filter method.

But I am getting error.

Here is my try (I am filtering by SubProjectName)

    <li ng-repeat="project in projectNames | unique: 'SubProjectName' ">

AngularJS doesn't include a unique filter by default. You can use the one from angular-filter. Just include the JavaScript

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-filter/0.5.8/angular-filter.min.js"></script>

and include the dependeny in your app:

var app = angular.module('myApp', ['angular.filter']);

Your code should work right away! I edited your Plunker so it works.

I think you are looking for an answer like this

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.Id = "1";
  $scope.SubProjectName="Retail Building";

.filter('unique', function() {
  return function(projects, subProjectName) {
    var newprojects =[];
      if(project.SubProjectName === subProjectName)
    return newprojects;

<li ng-repeat="project in projectNames | unique:SubProjectName">{{project.SubProjectName}}</li>


The unique filter you are probably attempting to use comes from AngularUI, so you need to include it:

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.js"></script>

and add it as module dependency:

var app = angular.module('plunker', ['ui.filters']);

I have updated your plunkr as http://plnkr.co/edit/sx3u1ukH9752oR1Jfx6R?p=preview added filter dependency

var app = angular.module('plunker', ['angular.filter']);

Hope this may help you
