I've been working on implementing a collapsible menu on a website, but I'm running into issues with the toggle button. The button appears fine, but it's not responding when clicked.
I must be overlooking something simple. Any assistance would be greatly appreciated!
<nav class="navbar-default" role="navigation">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header ">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<div class="col-md-4 logo">
<h1><a href="index.php"></a></h1>
</div><!--.logo-->
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse navbar-ex1-collapse">
<ul class="nav navbar-nav">
<ul>
<li><a class="about" href="#">About</a></li>
<li><a class="products" href="#">Products</a></li>
<li><a class="technology" href="#">Technology</a></li>
</ul>
</ul>
</div><!-- /.navbar-collapse -->
</nav>
