Bootstrap 3 multiple menus collapse into one for mobile

Question

I have been fighting with menus for a while now. What I want is both a top menu and a side menu. And in order to be useful on mobile devices, both menus need to collapse into something accessible on a phone. Is this actually possible? Or do I have to code different solutions for the different screen sizes?

Thanks

html

<nav class="navbar 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="#bs-example-navbar-collapse-1">
      <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="#">Brand</a>
  </div>

  <!-- Collect the nav links, forms, and other content for toggling -->
  <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Link</a></li>
      <li><a href="#">Link</a></li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
        <ul class="dropdown-menu">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li class="divider"></li>
          <li><a href="#">Separated link</a></li>
          <li class="divider"></li>
          <li><a href="#">One more separated link</a></li>
        </ul>
      </li>
    </ul>
    <form class="navbar-form navbar-left" role="search">
      <div class="form-group">
        <input type="text" class="form-control" placeholder="Search">
      </div>
      <button type="submit" class="btn btn-default">Submit</button>
    </form>
    <ul class="nav navbar-nav navbar-right">
      <li><a href="#">Link</a></li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
        <ul class="dropdown-menu">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li class="divider"></li>
          <li><a href="#">Separated link</a></li>
        </ul>
      </li>
    </ul>
  </div><!-- /.navbar-collapse -->
</nav>
<div class="container">
    <div class="row">
        <section class="col-sm-9">content</section>
        <aside id="sidebar" class="col-sm-3 hidden-xs">

        <ul class="nav nav-pills nav-stacked">
          <li><a href="#">Home</a></li>
          <li><a href="#">Profile</a></li>
          <li><a href="#">Messages</a></li>
        </ul>


        </aside>
    </div>
</div>

javascript

$('#bs-example-navbar-collapse-1').on('show.bs.collapse', function () {
  $('#bs-example-navbar-collapse-1').append($('#sidebar').html());
  $('#bs-example-navbar-collapse-1 ul').last().removeClass('nav-pills nav-stacked').addClass('navbar navbar-nav');
});
$('#bs-example-navbar-collapse-1').on('hidden.bs.collapse', function () {
  $('#bs-example-navbar-collapse-1 ul:last-child').remove();
});
$(window).on('resize', function () {
  if (window.innerWidth > 768) {$('#bs-example-navbar-collapse-1').collapse('hide');}
});

Example: http://bootply.com/106921

The (navbar) collapse triggers some events: hidden, hide, show and shown. (see: http://getbootstrap.com/javascript/#collapse) use this events to append the content of your side menu to the navbar. Remove it again on hidden: remove last append element jquery

Hide your side menu on small devices with the Responsive utilities (http://getbootstrap.com/css/#responsive-utilities).

The last "problem" collapse hide isn't triggerd on window resize will be solved here: https://github.com/twbs/bootstrap/issues/11653
