theme 221 script part

ADD THIS JQUERY SCRIPT IF YOU DON'T HAVE IT YET:

<!-- for the click and custom icons -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

FOR THE ICONS WORK:

<!-- the custom icons -->
<script src="https://unpkg.com/feather-icons"></script>


THIS PART GOES BETWEEN A <script></script> OR <script type="text/javascript"></script>. if you don't have one, you can create at the top in the <meta> tag or at the end before </html>:

//    update-toggle
$(document).ready(function() {
$(".toggle-content").hide();
    $(".toggle-link").click(function(event) {
    event.preventDefault();
    $(this).next(".toggle-content").slideToggle(500);
    });
});

//              feather icons (custom icons)
    feather.replace();
