I would like to adapt my code to create a submenu like this one: link for example in "categories" - "css" then another side menu appears with the same properties as above and I would like mine to be like this.
<div id="menu2">
<ul id="menu">
<li><a href="site.html">Pagina Inicial</a></li>
<li>
<a href="#">Produtos</a>
<ul>
<li><a href="inserir.html">Inserir</a></li>
<li><a href="#" class="last-child">Ver produtos no site</a>
<ul>
<li><a href="#">Caps</a></li>
<li><a href="#">Camisas</a></li>
</ul>
<li><a href="procurar.html">Procurar</a></li>
<li><a href="remover.html">Eliminar</a></li>
<li><a href="listar.php">Listar</a></li>
</ul>
</li>
<li>
<a href="site.html">A nossa Empresa</a>
<ul>
<li><a href="empresa.html">História</a></li>
<li><a href="val.html">Valores</a></li>
<li><a href="maps.html">Localização</a></li>
</ul>
</li>
<li><a href="cont.html">Contactos</a>
<ul>
<li><a href="email.html">Contacte-nos </a></li>
</ul>
</li>
</ul>
</div>
