            </ul>
          </li>

          <li>
            <ul>
              <li><div>Node 1.1.2.1</div></li>
              <li><div>Node 1.1.2.2</div></li>
              <li><div>Node 1.1.2.3</div></li>
            </ul>
          </li>
        </ol>
      </li>
      <li>
        <ol>
          <li><div>Node 1.2.1</div></li>
          <li><div>Node 1.2.2</div></li>
          <li><div>Node 1.2.3</div></li>
        </ol>
      </li>
      <li><div>Node 1.3
        <p>N’importe quoi ici.</p>
        </div></li>
    </ul>
  </li>
  <li>
    <ul>
      <li><div>Node 2.1</div></li>
      <li><div>Node 2.2
        <p>Put something right here.</p>
      </div></li>
      <li><div>Node 2.3</div></li>
    </ul>
  </li>
  <li><div>Node&nbsp;3</div></li>  
</ol>
