For those interested - Here is another way of implementing this without Bootstrap's javascript.

Import Angular's UI-Bootstrap.

HTML:

<div class="navbar navbar-inverse" ng-controller="NavBarCtrl">
<div class="navbar-inner">
    <div class="container">
        <button class="btn btn-navbar" ng-click="isCollapsed = !isCollapsed"> 
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
        </button> <a class="brand" href="#">Short Course</a>
        <div class="nav-collapse" uib-collapse="isCollapsed">
            <ul class="nav">
                <li><a href="#"><i class="icon-home icon-white"></i> Home</a>
                </li>
                <li><a href="#">Lessons</a>
                </li>
                <li><a href="#">Grades</a>
                </li>
            </ul>
            <ul class="nav pull-right">
                <li><a href="#/class"><i class="icon-upload icon-white"></i> Upload/Save</a>
                </li>
                <li><a href="#/class"><i class="icon-off icon-white"></i> Save/Logout</a>
                </li>
            </ul>
        </div>
        <!-- /.nav-collapse -->
    </div>
</div>
<!-- /navbar-inner -->
</div>

JS:

var myApp = angular.module('myApp', ['ui.bootstrap']);

function NavBarCtrl($scope) {
    $scope.isCollapsed = true;
}

This was a tricky one. The docs showed one way, and it functions great. I copied the docs example (http://twitter.github.com/bootstrap/components.html#navbar) and tried using it. I then went to the examples page and tried the layout listed here: http://twitter.github.com/bootstrap/examples/fluid.html

The one and only difference was a <button> instead of <a>

<button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">

Instead of

<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">

I don't know why, but changing that made it function great.

EDIT

Arbiter pointed out that the <a /> was missing the href='#' attribute. Adding that attribute would also solve the problem.

No need to engage a controller. Just use ng-init instead to initialize the isCollapsed flag when template is initially compiled.

<div class="navbar navbar-inverse" ng-controller="NavBarCtrl">
<div class="navbar-inner">
    <div class="container">
        <button class="btn btn-navbar" ng-init="isCollapsed = true" ng-click="isCollapsed = !isCollapsed"> 
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
        </button> <a class="brand" href="#">Short Course</a>
        <div class="nav-collapse" collapse="isCollapsed">
            <ul class="nav">
                <li><a href="#"><i class="icon-home icon-white"></i> Home</a>
                </li>
                <li><a href="#">Lessons</a>
                </li>
                <li><a href="#">Grades</a>
                </li>
            </ul>
            <ul class="nav pull-right">
                <li><a href="#/class"><i class="icon-upload icon-white"></i> Upload/Save</a>
                </li>
                <li><a href="#/class"><i class="icon-off icon-white"></i> Save/Logout</a>
                </li>
            </ul>
        </div>
        <!-- /.nav-collapse -->
    </div>
</div>
<!-- /navbar-inner -->
</div>

Just adding jquery.min.js and bootstrap.min.js to the index.html file solved this problem.

For collapsable navigation we need to include jquery.min.js and bootstrap.min.js

Answer 5

I feel that this will be simple JS fix:

//for close, opened dropdown.
$(".nav a").click(function () {
    if ($(".navbar-collapse").hasClass("in")) {
        $('[data-toggle="collapse"]').click();
    }
});

If this code is not working correctly then see that it's binding correctly, so place it in controller that loads page.

Here is a working implementation using the ui.bootstrap.collapse module. https://jsfiddle.net/7z8hLuyu/

HTML

<div ng-app="app">
<nav class="navbar navbar-default">
  <div class="container-fluid" ng-controller="NavigationCtrl as vm">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" ng-click="vm.toggleCollapse()">
        <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="navbar-collapse" style="overflow:hidden!important;" uib-collapse="vm.    isCollapsed">
      <ul class="nav navbar-nav">
    <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></    li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link 2</a></li>
        <li><a href="#">Link 3</a></li>
        <li><a href="#">Link 4</a></li>     
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>
</div>

Controller (using controllerAs syntax):

(function(){
    'use strict';

  angular
    .module('app', ['ngAnimate','ui.bootstrap.collapse'])
    .controller('NavigationCtrl', NavigationCtrl);

  NavigationCtrl.$inject = [];

  function NavigationCtrl() {
    var vm = this;
    vm.isCollapsed = true;
    vm.toggleCollapse = toggleCollapse;

    function toggleCollapse() {
        vm.isCollapsed = !vm.isCollapsed;
    }
  }

})();

Note: for animation to work in ui.bootstrap modules, you must include ngAnimate.
