title: Angularjs appended properties in drop down with spaces
body: <p>I want to show spaces in the div options which I am appending multiple properties.
  The spaces are not shown.
  Below is my code</p>
  
  <pre><code>&lt;select id="sel" class="input-block-level" ng-model="list_category" ng-options="obj.id as (obj.name + '    ' + obj.id) for obj in list_categories.data"&gt;    
          &lt;option value=""&gt;Other&lt;/option&gt;
      &lt;/select&gt;
  var app = angular.module('app', []);
  function Ctrl($scope) {  
      $scope.list_categories = {
          data: [{
              id: 'id1',
              name: 'name1'
          }, {
              id: 'id2',
              name: 'name2'
          }]
      };       
      $scope.list_category = 'id2';
  }
  </code></pre>
