I am struggling to add an additional drop-down menu to my navigation bar. How can I place a new one on top of the existing menu?
<ul class="menu">
<li>
Toggle navigation
<ul class="submenu">
<li>CUSTOM SIGNS</li>
<li>DIGITAL PRINTING</li>
<li>SERVICES</li>
</ul>
</li>
<li role="presentation">
<a href="# untitled.html" id="getanestimate">get an estimate</a>
</li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="false">industry showcase <span class="caret"></span></a>
<ul class="dropdown-menu" role="menu">
<li role="presentation"><a href="services.html">Price Package</a></li>
<li role="presentation"><a href="#">Order Services</a></li>
<li role="presentation"><a href="#">Custom Request</a></li>
</ul>
</li>
<li role="presentation"><a href="#untitled.html">gallery</a></li>
<li role="presentation"><a href="contact.html">about us </a></li>
</ul>
