Within my ng-repeat loop, I have a drop-down menu and an add button that allows users to add new drop-down menus to the list. However, I am looking for a way to restrict the second drop-down menu from selecting the same value as the first one. In other words, I want to prevent the second drop-down menu from selecting the same value that has already been selected in the first drop-down menu.
Pankaj Parkar provided an answer to a similar question of mine, but I am struggling to implement it in my JSFiddle code.
ng-repeat="post in posts | filter: { type: selectedValue }"
I would greatly appreciate any assistance with this issue.

var app = angular.module('angularjs-starter', []);
app.controller('MainCtrl', function($scope) {
$scope.names = ['Mobile','Office','Home'];
$scope.choices = [{id: 'choice1'}];
$scope.addNewChoice = function() {
var newItemNo = $scope.choices.length+1;
$scope.choices.push({'id':'choice'+newItemNo});
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="angularjs-starter" ng-controller="MainCtrl">
<fieldset ng-model='y' ng-repeat="choice in choices">
<select>
<option ng-model='x1' ng-repeat = "x in names">{{x}}</option>
</select>
</fieldset>
<button class="addfields" ng-click="addNewChoice()">Add fields</button>
</div>
