First markup your items like so. You'll want to mark any submenus with the "accordion" class.

<ul class="accordion">
  <li><a class="head" href="#">Item 1</a>
      <ul class="accordion">
      <li><a href="#">Item 1 - 1 </a></li>
      <li><a href="#">Item 1 - 2</a></li>
      <li>
        <a href="#">Item 1 - 3</a>
        <ul class="accordion">
          <li><a href="#">Item 1 - 3 - 1</a></li>
          <li><a href="#">Item 1 - 3 - 1 </a></li>
          <li><a href="#">Item 1 - 3 - 1</a></li>
        </ul>
      </li>
    </ul>
  </li>
  <li><a href="#">Item 2</a></li>
  <li>
    <a href="#">Item 3</a>
    <ul class="accordion">
      <li><a href="#">Item 3 - 1 </a></li>
      <li><a href="#">Item 3 - 2</a></li>
      <li><a href="#">Item 3 - 2</a></li>
    </ul>
  </li>
</ul>

After that just use jQuery UI's accordion plugin (Don't forget to include the jQuery core file and jQuery UI file.

<script type="text/javascript">
    $(function() {
        $(".accordion").accordion();
    });
</script>

Use CSS to style as required. Of course, the structures and the class names can be changed as preferred. This is just the easiest solution

This is also a good option for nested level accordion using Jquery:

 $('.toggle').click(function(e) { e.preventDefault(); var $this = $(this); if ($this.next().hasClass('show')) { $this.next().removeClass('show'); $this.next().slideUp(350); } else { $this.parent().parent().find('li .inner').removeClass('show'); $this.parent().parent().find('li .inner').slideUp(350); $this.next().toggleClass('show'); $this.next().slideToggle(350); } }); 

 * { box-sizing: border-box; font-family: 'Open Sans', sans-serif; font-weight: 300; } a { text-decoration: none; color: inherit; } p { font-size: 1.1em; margin: 1em 0; } ul { list-style: none; padding: 0; } ul .inner { padding-left: 1em; overflow: hidden; display: none; } ul .inner.show { /*display: block;*/ } ul li { margin: 0.5em 0; } ul li a.toggle { width: 100%; display: block; background: rgba(0, 0, 0, 0.78); color: #fefefe; padding: 0.75em; border-radius: 0.15em; transition: background 0.3s ease; } ul li a.toggle:hover { background: rgba(0, 0, 0, 0.9); }
