bootstrap navbar in single page app - html

Question

I have a problem with Bootstrap's navbar: https://jsfiddle.net/2wwgt3to/1/
I'm making single page application and it turns out that bootstraps dropdown navigation menu for mobile is not really working well with it i.e. its not collapsing after clicking, I managed to solve this with adding data-toggle="collapse" data-target="#navbar" attributes but then the whole menu is collapsing even when it is not in dropdown form.

Answer 1

Remove data-toggle="collapse" data-target="#navbar" from
<div data-toggle="collapse" data-target="#navbar" id="navbar" class="navbar-collapse collapse">
Edited code:
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Project name</a>
</div>
<div id="navbar" class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li>About</li>
<li>Contact</li>
<li class="dropdown">
Dropdown <span class="caret"></span>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li>Separated link</li>
<li>One more separated link</li>
</ul>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li>Default</li>
<li>Static top</li>
<li class="active">Fixed top <span class="sr-only">(current)</span></li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>
