Hi everyone, On the website https://www.fotoexpositie.nl I have a menu that reverts to a drop-down menu on mobile screens. Except that it's not 'dropping' for some reason. I've tried code-checkers and manually checking the code but can't find anything wrong with it. Except ... that it's not working. Hope anyone can help out! Thanks so much and for everyone happy holidays! Thanks, Peter The website can be found at: https://www.fotoexpositie.nl Don't know it it helps but the menu code is: <nav class="navbar navbar-inverse" style="border-radius:0px;"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#"><font color="#ffffff">Foto</font><font color="#80ff00">expositie</font><font color="#ffffff">.nl</font></a> </div> <div class="collapse navbar-collapse" id="myNavbar"> <ul class="nav navbar-nav"> <li><a href="exposities/index.html">Exposities</a></li> <li><a href="nieuws/index.html">Nieuws</a></li> <li><a href="fotografen/index.html">Fotografen</a></li> <li><a href="opleidingen/index.html">Opleidingen</a></li> <li><a href="linkpartners.html">Linkpartners</a></li> </ul> </div> </div> </nav>
