title: Is there any way in angular 6 to get ViewChildren deep?
body: <p>is there any way to get the children from a subcomponent?</p>
  
  <p>Imagine the following component tree:</p>
  
  <ul>
  <li>App
  
  <ul>
  <li>Question
  
  <ul>
  <li>Question Option (contains a checkbox)</li>
  <li>Question Option (contains a checkbox)</li>
  <li>Question Option (contains a checkbox)</li>
  </ul></li>
  </ul></li>
  </ul>
  
  <p>I want to access <code>Question Option</code> from <code>App</code> to check all checkboxes.</p>
