A tiny jQuery extension for Bootstrap framework that helps developers create multi-level dropdowns inside your navbar and converts them into an accordion on the mobile device for better readability.

How to use it:

1. Create a multi-level dropdown component from nested HTML lists in your navbar as follows.

<!-- Required -->
<link rel="stylesheet" href="/path/to/cdn/bootstrap.min.css" />
<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/cdn/bootstrap.min.js"></script>
<li class="nav-item dropdown">
  <a class="nav-link dropdown-toggle" href="#" data-toggle="dropdown">Services</a>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#"> Web Development &raquo </a>
      <ul class="submenu dropdown-menu">
        <li><a class="dropdown-item" href="#"> Wordpress Website </a></li>
        <li><a class="dropdown-item" href="#"> Website Design </a></li>
        <li><a class="dropdown-item" href="#"> Open Source </a></li>
        <li><a class="dropdown-item" href="#"> Custom CMS </a></li>
    <li><a class="dropdown-item" href="#"> Software Development &raquo </a>
      <ul class="submenu dropdown-menu">
        <li><a class="dropdown-item" href="#"> Android App </a></li>
        <li><a class="dropdown-item" href="#"> Windows Software </a></li>
    <li><a class="dropdown-item" href="#"> Designing &raquo </a>
       <ul class="submenu dropdown-menu">
        <li><a class="dropdown-item" href="#"> Web Designing </a></li>
        <li><a class="dropdown-item" href="#"> UI Design </a></li>
        <li><a class="dropdown-item" href="#"> Wireframing </a></li>
    <li><a class="dropdown-item" href="#"> SEO </a></li>
    <li><a class="dropdown-item" href="#"> Management </a>

2. The jQuery script to prevent closing from click inside the dropdown.

$(document).on('click', '.dropdown-menu', function (e) {

3. Convert the multi-level dropdown into an accordion when running on a small screen device (screen width < 992px in this example).

if ($(window).width() < 992) {
  $('.dropdown-menu a').click(function(e){
    if($(this).attr('href') == '#')
    $('.dropdown').on('', function () {

4. The necessary CSS styles for the Multi-level Dropdown.

@media (min-width: 992px){
  .dropdown-menu .dropdown-toggle:after {
    border-top: .3em solid transparent;
    border-right: 0;
    border-bottom: .3em solid transparent;
    border-left: .3em solid;
  .dropdown-menu .dropdown-menu{
    margin-left:0; margin-right: 0;
  .dropdown-menu li{
    position: relative;
  .nav-item .submenu{ 
    display: none;
    position: absolute;
    left:100%; top:-7px;
  .nav-item .submenu-left{ 
    right:100%; left:auto;
  .dropdown-menu > li:hover{ background-color: #f1f1f1 }
  .dropdown-menu > li:hover > .submenu{
    display: block;
