<div class="container">
  <div class="navbar-header">
    <button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".js-navbar-collapse">

      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>

Thank you in advance.

Try this:

$('nav ul ul.dropdown-menu').removeClass('row fluid-container').addClass('container');
$(window).on('resize',function(){
  $('nav ul ul.dropdown-menu').css({padding:$('.container').css('margin')})
});
