How to use it:

1. If you're running the plugin in Bootstrap 4 project, load 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">
        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown"
            aria-haspopup="true" aria-expanded="false">
            Dropdown
        </a>
        <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
          <li><a class="dropdown-item" href="#">Action</a></li>
          <li><a class="dropdown-item" href="#">Another action</a></li>
          <div class="dropdown-divider"></div>
          <li></li><a class="dropdown-item" href="#">Something else here</a></li>
          <li class="nav-item dropdown">
            <a class="dropdown-item dropdown-toggle" href="#" id="navbarDropdown1" role="button" data-toggle="dropdown"
                aria-haspopup="true" aria-expanded="false">
              Dropdown
            </a>
            <ul class="dropdown-menu" aria-labelledby="navbarDropdown1">
              <li><a class="dropdown-item" href="#">Action</a></li>
              <li><a class="dropdown-item" href="#">Another action</a></li>
              <div class="dropdown-divider"></div>
              <li></li><a class="dropdown-item" href="#">Something else here</a></li>
              <li class="nav-item dropdown">
                <a class="dropdown-item dropdown-toggle" href="#" id="navbarDropdown2" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                  Left Dropdown
                </a>
                <ul class="dropdown-menu left" aria-labelledby="navbarDropdown2">
                  <li><a class="dropdown-item" href="#">Action</a></li>
                  <li><a class="dropdown-item" href="#">Another action</a></li>
                  <div class="dropdown-divider"></div>
                  <li></li><a class="dropdown-item" href="#">Something else here</a></li>
                </ul>
              </li>
            </ul>
          </li>
        </ul>
      </li>
    </ul>
  </div>
</nav>
