title: "lock" a portion of HTML in wysiHTML5
body: <p>I'm using <a href="https://github.com/xing/wysihtml5" rel="nofollow">https://github.com/xing/wysihtml5</a> for an editor in my code base and I'd like to "lock" portions of the code to not be editable, like so: </p>
  
  <pre><code>&lt;form&gt;
  &lt;textarea id="wysihtml5-textarea" placeholder="Enter your text ..." autofocus&gt;
  
  &lt;div&gt;Some Editable Text here :) &lt;/div&gt;
  
  &lt;div class="lockedForEditing" contenteditable="false"&gt;YOU CAN'T EDIT ME!!!&lt;/div&gt;
  
  &lt;div&gt;Some More editable code here &lt;/div&gt;
  
  &lt;/textarea&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Does anyone know if this is possible?  I've tried several ways so far with no success.  I've also not seen anything in the documentation.  If this isn't possible, do you know a similar editor where it is possible? </p>
