Responsive dropdown navbar with angular-ui bootstrap (done in the correct angular kind of way)

I've created a JSFiddle with a dropdown navbar using angular-ui-boostrap's module "ui.bootstrap.dropdownToggle": http://jsfiddle.net/mhu23/2pmz5/

<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
    <div class="container"> <a class="brand" href="#">
                My Responsive NavBar
            </a>

        <ul class="nav">
            <li class="divider-vertical"></li>
            <li class="dropdown"> <a href="#" class="dropdown-toggle">
                        Menu 1 <b class="caret"></b>
                    </a>

                <ul class="dropdown-menu">
                    <li><a href="#/list">Entry 1</a>
                    </li>
                    <li><a href="#/list">Entry 2</a>
                    </li>
                </ul>
            </li>
          ....
        </ul>
    </div>
</div>
</div>

As far as I understand this is the proper, angular kind of way to implement such a dropdown menu. The "wrong" way, in terms of angularjs, would be to include bootstrap.js and to use "data-toggle="dropdown"... Am I right here?

Now I'd like to add responsive behaviour to my navbar as done in the following Fiddle: http://jsfiddle.net/ghtC9/6/

BUT, there's something I don't like about the above solution. The guy included bootstrap.js!

So what would be the correct angular kind of way to add responsive behaviour to my existing navbar?

I obviously need to use bootstraps responsive navbar classes such as "nav-collapse collapse navbar-responsive-collapse". But I don't know how...

I'd really appreciate your help!

Thank you in advance! Michael

Based on antoinepairet's comment/example:

Using uib-collapse attribute provides animations: http://plnkr.co/edit/omyoOxYnCdWJP8ANmTc6?p=preview

<nav class="navbar navbar-default" role="navigation">
    <div class="navbar-header">

        <!-- note the ng-init and ng-click here: -->
        <button type="button" class="navbar-toggle" ng-init="navCollapsed = true" ng-click="navCollapsed = !navCollapsed">
            <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>

    <div class="collapse navbar-collapse" uib-collapse="navCollapsed">
        <ul class="nav navbar-nav">
        ...
        </ul>
    </div>
</nav>

Ancient..

I see that the question is framed around BS2, but I thought I'd pitch in with a solution for Bootstrap 3 using ng-class solution based on suggestions in ui.bootstrap issue 394:

The only variation from the official bootstrap example is the addition of ng- attributes noted by comments, below:

<nav class="navbar navbar-default" role="navigation">
  <div class="navbar-header">

    <!-- note the ng-init and ng-click here: -->
    <button type="button" class="navbar-toggle" ng-init="navCollapsed = true" ng-click="navCollapsed = !navCollapsed">
      <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>

  <!-- note the ng-class here -->
  <div class="collapse navbar-collapse" ng-class="{'in':!navCollapsed}">

    <ul class="nav navbar-nav">
    ...

Here is an updated working example: http://plnkr.co/edit/OlCCnbGlYWeO7Nxwfj5G?p=preview (hat tip Lars)

This seems to works for me in simple use cases, but you'll note in the example that the second dropdown is cut off… good luck!

You can do it using the "collapse" directive: http://jsfiddle.net/iscrow/Es4L3/ (check the two "Note" in the HTML).

        <!-- Note: set the initial collapsed state and change it when clicking -->
        <a ng-init="navCollapsed = true" ng-click="navCollapsed = !navCollapsed" class="btn btn-navbar">
           <span class="icon-bar"></span>
           <span class="icon-bar"></span>
           <span class="icon-bar"></span>
        </a>
        <a class="brand" href="#">Title</a>
           <!-- Note: use "collapse" here. The original "data-" settings are not needed anymore. -->
           <div collapse="navCollapsed" class="nav-collapse collapse navbar-responsive-collapse">
              <ul class="nav">

That is, you need to store the collapsed state in a variable, and changing the collapsed also by (simply) changing the value of that variable.

Release 0.14 added a uib- prefix to components:

https://github.com/angular-ui/bootstrap/wiki/Migration-guide-for-prefixes

Change: collapse to uib-collapse.

Not sure if anyone is having the same responsive issue, but it was just a simple css solution for me.

same example

...  ng-init="isCollapsed = true" ng-click="isCollapsed = !isCollapsed"> ...
...  div collapse="isCollapsed"> ...

with

@media screen and (min-width: 768px) {
    .collapse{
        display: block !important;
    }
}
