Bootstrap, WordPress & NavWalker - Nav top level links not working

I understand that this question has been addressed in other posts, however I am having issues with top server links not working on this site .

This is a WordPress site built on BootStrap 3 and uses NavWalker to integrate WordPress navigation into the Bootstrap framework. Here is the navigation code:

 <div class="navbar navbar-default col-md-9" role="navigation">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target=".navbar-collapse">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>

        </div>
        <?php
                        wp_nav_menu( array(
                        'menu'                    => 'Primary',
                        'theme_location'    => 'Primary',
                        'depth'                   => 2,
                        'container'             => 'div',
                        'container_class'    => 'collapse navbar-collapse col-md-9',
                        'container_id'        => 'none',
                        'menu_class'         => 'nav navbar-nav',
                        'fallback_cb'         => 'wp_bootstrap_navwalker::fallback',
                        'walker'                => new wp_bootstrap_navwalker())
                        );
                    ?> 
        </div><!-- /.container -->
</div><!-- /.navbar -->

      

        
        
        
      

    

As a consequence, the hover function is missing, which is good for dropdown menus. I approached this with the following wpeden solution :

( function( $ ) {
jQuery(function($) {
$('.navbar .dropdown').hover(function() {
$(this).find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();

}, function() {
$(this).find('.dropdown-menu').first().stop(true, true).delay(100).slideUp();

});

$('.navbar .dropdown > a').click(function(){
location.href = this.href;
});

});
} )( jQuery );

      

        
        
        
      

    

This is a very nice job displaying the dropdown navigation gracefully, but there are no active elements in the parent elements.

I have verified that the parent does indeed have active links, pushing them out of the childless navigation hierarchy where they render links correctly, so there is something missing that I cannot identify and appreciate a sharp eye or two to help identify it ...
