<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<img src="{$favlogo}" alt="" width="8%" height="auto">
<li class="hvr-bounce-to-bottom active">{$homebar}</li>
<li class="hvr-bounce-to-bottom">{$aboutUs}</li>
<li class="hvr-bounce-to-bottom">{$servicos}</li>
<li class="hvr-bounce-to-bottom">{$galeria}</li>
<li class="hvr-bounce-to-bottom">{$equipa}</li>
<li class="hvr-bounce-to-bottom">{$contactUs}</li>
<li class="hvr-bounce-to-bottom">{$user}</li>

<li class="hvr-bounce-to-bottom">{$logout}</li>
<li class="hvr-bounce-to-bottom">{$email}</li>
<li class="hvr-bounce-to-bottom">{$contacto}</li>
<li class="dropdown">
Idioma
<div class="dropdown-content">
{$DEN}
{$DPT}
{$DES}
</div>
</li>
</ul>
<div class="clearfix"> </div>
</div>
</div>
</nav>
</div>
And here is the Controller code for this part
$data['DPT'] = 'Português';
$data['DEN'] = 'English';
$data['DES'] = 'Español';
//------------------ FOOTER ----------------------
$data['footercontactUS'] = 'Contacte-nos';
$data['footeraboutUS'] = 'Sobre Nós';
return $data;
