Question

How can I add submenu to the following sidenav?
<ul class="sidenav sidenav-fixed" id="nav-mobile" style="width:250px">
<li> Text here</li>
<li>
<div class="divider"></div>
</li>
<li>
<a onclick="load('home')"><i class="material-icons">home</i>Home</a>
</li>
<li><a onclick="load('intro')"><i class="material-icons">apps</i>Content Table</a></li>
</ul>

Answer 1

MaterializeCSS documentation site uses a collapsible inside the sidenav:
https://materializecss.com/collapsible.html
Collapsible is a separate component that also needs initialising:
document.addEventListener('DOMContentLoaded', function() {
var elems = document.querySelectorAll('.collapsible');
var instances = M.Collapsible.init(elems);
});
Working codepen:

The actual markup taken from the Materialize doc site is:
<!-- Start nested content -->
<li>
<ul class="collapsible collapsible-accordion">
<li>
<a class="collapsible-header waves-effect waves-teal" tabindex="0"><i class="material-icons">menu</i>Nested</a>
<div class="collapsible-body">
<ul>
<li>Color</li>
<li>Grid</li>
<li>Helpers</li>
<li>Media</li>
<li>Pulse</li>
<li>Sass</li>
<li>Shadow</li>
<li>Table</li>
<li>Transitions</li>
<li>Typography</li>
</ul>
</div>
</li>
</ul>
</li>

Answer 2

You can do something like below with MaterializeCSS
<div id="slide-out" class="sidenav" style="transform: translateX(0%);">
<ul class="collapsible">
<li class="active">
<div class="collapsible-header">
Group1
</div> <div class="collapsible-body" style="display: block;">
<li>Course 1</li>
<li>Course 2</li>
</div>
</li>
<li class="">
<div class="collapsible-header">
केंद्रीय लोकसेवा आयोग
</div>
<div class="collapsible-body" style="">
</div>
</li>
</ul>
</div>
