how to position items vertically in navbar - asp.net

Question

In my bootstrap-based ASP.NET application, I need to show navigational links (Home, About, etc.) on the right of the navbar. I also need to have a search button below the nav links. The button must be right-aligned with the right-most nav link. Here is the code that I tried:
<div class="navbar-collapse collapse navbar-right">
<ul class="nav navbar-nav">
<li>#Html.ActionLink("Home", "Index", "Home")</li>
<li>#Html.ActionLink("About", "About", "Home")</li>
<li>#Html.ActionLink("Contact", "Contact", "Home")</li>
</ul>
<div class="col-sm-3 col-md-3 navbar-right">
<form class="navbar-form" role="search" method="get" action="~/Home/Search">
<div class="input-group ">
<input type="text" class="form-control" placeholder="Search" id="term" name="term" />
<div class="input-group-btn">
<button class="btn btn-default" type="submit"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</div>
</div>
However, the search button is still shown on the same row as the nav links.
How do I get items to vertically right-align in the navbar? Regards.

Just wrap the form in a new container, see this demo (also, I made edits to the structure to correct it):
<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" 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>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-right">
<li>Link</li>
<li>Link</li>
<li>Link</li>
</ul>
</div>
</div>
<div class="container-fluid">
<div class="navbar-collapse collapse">
<form class="navbar-form navbar-right" role="search" method="get" action="~/Home/Search">
<div class="input-group ">
<input type="text" class="form-control" placeholder="Search" id="term" name="term">
<div class="input-group-btn">
<button class="btn btn-default" type="submit"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</div>
</div>
</nav>
