title: ng-model return value as an array?
body: <p>I'm new to Angular.
  I'm finding a way to return the ng-model value as an array.</p>
  
  <pre><code>&lt;select ng-options="district.name for district in districts" ng-model="district"&gt;&lt;/select&gt;
  
  $scope.districts = [
      {
        name: 'A'
      },
      {
        name: 'B'
      },
      {
        name: 'C'
      }
  ]
  </code></pre>
  
  <p>So it will store an Object in <code>district</code> when I select one of the option. </p>
  
  <pre><code>{
   name: 'A'
  }
  </code></pre>
  
  <p>But what I want is an Array storing Object. Just like</p>
  
  <pre><code>[
    {
     name: 'A'
    }
  ]
  </code></pre>
  
  <p>I found that <code>select[multiple]</code> is doing what I want. So I wonder is there any build-in method can do this on a single selection.</p>
