title: Angular 5 - Disabling Radio Buttons
body: <p>I have a radio button group in Angular 5. I want to disable some options, using the <code>[disabled]</code> attribute. However, I am noticing only the first radio button actually gets disabled. See my plunker: <a href="http://plnkr.co/edit/JzFmvjUyvhPdTkbYT1YZ?p=preview" rel="noreferrer">http://plnkr.co/edit/JzFmvjUyvhPdTkbYT1YZ?p=preview</a></p>
  
  <p>Even if I hard code <code>[disabled]="true"</code>, it still doesn't disable the second radio button. I don't want to switch to using a <code>&lt;select&gt;</code>, so I am curious if there is another way to get this to work with radio buttons.</p>
