title: How to throw an error if markdown editor left empty in the form?
body: <p>I have used a markdown editor in my angular HTML file form as follows:</p>
  
  <pre><code>        &lt;td-text-editor class="full-width" formControlName="description"&gt;&lt;/td-text-editor&gt;
  </code></pre>
  
  <p>In the form, if we leave the description empty, it should throw up an error. Any inputs?</p>
