Bootstrap Horizontal multilevel Menu

Question

Is there any way to create a horizontal multilevel menu structure using bootstrap I haven't seen any multilevel menus with Horizontal orientation . If not i have to use some external css and styles to generate this kind of menu . A sample structure of the menu structure is similar to this

Answer 1

<nav class="navbar navbar-default" role="navigation">
  <!-- Brand and toggle get grouped for better mobile display -->
  <div class="navbar-header">
    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
      <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>

  <!-- Collect the nav links, forms, and other content for toggling -->
  <div class="collapse navbar-collapse navbar-ex1-collapse">
