How to use it:

1. The plugin requires the Animate.css to animate the dropdown menus on hover.

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.7.0/animate.min.css">

2. Include the jQuery BootBavbar plugin's files on your Bootstrap page.

<link rel="stylesheet" href="css/bootnavbar.css">
<script src="js/bootnavbar.js" ></script>

3. Add sub dropdowns to the navbar using nested HTML lists as follows.

<nav class="navbar navbar-expand-lg navbar-light bg-light" id="main_navbar">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
      aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item dropdown">

            aria-haspopup="true" aria-expanded="false">
