title: Set selected item selected option
body: <p>In my ionic project I have a <code>&lt;select&gt;</code> like so:</p>
  
  <pre><code>&lt;select ng-model="user.bloodType" ng-options="x as x.description for x in formData.bloodTypes"&gt;&lt;/select&gt;
  </code></pre>
  
  <p>So to clarify, <code>user.bloodType</code> is an object that looks like this:</p>
  
  <pre><code>{
    'id' : 1,
    'description' : 'O+'
  }
  </code></pre>
  
  <p><code>formData.bloodTypes</code> contains an array of the above depicted <code>bloodType</code> object. So here comes the problem - I know that <code>user.bloodType</code> is definitely one of the objects that is in <code>formData.bloodTypes</code>. How can I set the <code>&lt;select&gt;</code> to be pre-selected on whatever <code>user.bloodType</code> is? </p>
