I am using bootstrap navbar and I have a collapsible navbar. But I am facing a strange problem, whenever I open my site i.e mobile phone or tablet (actually for which devices I need the collapsible navbar), the button appears but I'm not able to open the navbar. This should not happen. If I click on the navbar button (three line button) nothing happens.
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#collapsable-nav" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div id="collapsable-nav" class="collapse navbar-collapse">
<ul id="nav-list" class="nav navbar-nav navbar-right">
<li>
<a href="menu-categories.html">
<span class="glyphicon glyphicon-cutlery"></span>
<br class="hidden-xs">Menu
</a>
</li>
<li>
<a href="#">
<span class="glyphicon glyphicon-info-sign"></span>
<br class="hidden-xs">About
</a>
</li>
<li>
<a href="#">
<span class="glyphicon glyphicon-certificate"></span>
<br class="hidden-xs">Awards
</a>
</li>
<li id="phone" class="hidden-xs">
<a href="tel:410-602-5008">
<span>410-602-5008</span>
</a>
<div>* We Deliver</div>
</li>
</ul>
</div>
Please check your jQuery version. I hope this will fix your problem. Here is demo link: https://codepen.io/shamimipt/pen/abLKRrx
