How to make use of it:

1. Include needed assets on the web page.

<link rel="stylesheet" href="/path/to/cdn/materialdesignicons.min.css">

<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>

2. Include the Side Navigation’s JavaScript and CSS on the web page.

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

3. Create the HTML for the aspect navigation.

4. Create toggle buttons in the content material if needed.

<button type="button" class="btn btn-primary btn-lg" id="btn-show"><i class="mdi mdi-eye-outline mr-3"></i>Show</button>
<button type="button" class="btn btn-primary btn-lg" id="btn-hide"><i class="mdi mdi-eye-off-outline mr-3"></i>Hide</button>

5. the default variables within the _variables.scss to customize the looks of the aspect navigation.

$width: 300px;
$color_background: #2b3a42;
$color_item: #9eb7c3;
$color_item_hilight: white;
$color_submenu_bg: #3a4d56;
$color_menu_icon_bg: #3a4d56;
$color_menu_icon_active: #38fbc7;
$color_border: #3a4d56;
