Html – Hide Twitter Bootstrap nav collapse on click

This is not a submenu dropdown, the category is class li as in the picture:

By selecting a category from the responsive menu (the template is just
one page), I want to hide nav collapse automatically when clicking.
Also stroll to use as navigation, since the template has only one
page. I seek a solution that does not affect it, here is the HTML code
of menu:

    <!-- NAVBAR
  ================================================== -->
<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      </a>
      <a class="brand" href="#">Carousel Demo</a>
      <div class="nav-collapse">
        <ul class="nav" >
          <li class="active"><a href="#home">Home</a></li>
          <li><a href="#about">About</a></li>
          <li><a href="#portfolio">Portfolio</a></li>
          <li><a href="#services">Services</a></li>
          <li><a href="#contact">Contact</a></li>
          <!-- dropdown -->
        </ul>
        <!-- /.nav -->
      </div>
      <!--/.nav-collapse -->
    </div>
    <!-- /.container -->
  </div>
  <!-- /.navbar-inner -->
</div>
<!-- /.navbar -->
