<div class="top-bar show-for-medium">

   <div class="row">

     <div id="responsive-menu">

        <div class="top-bar-right">

            <ul class="dropdown menu" data-dropdown-menu>

               <li>

                   <button type="button" class="button orange"></button>

                   <ul class="menu vertical">

                      <li>

                          <textarea placeholder="Insert Message"></textarea>

                       </li>

                   </ul>

                </li>

            </ul>

         </div>

      </div>

   </div>

</div>

Could you please help me? thanks
