I've a 3 level nested bootstrap accordion which is working fine, but I want a change in the panel-heading div where I can use a font-awesome icon fa fa-chevron-down when the accordion is opened (Without affecting the nested accordions) and fa fa-chevron-right when accordion is collapsed. I'm using this code to changing the icon:
$('div.panel-collapse.collapse').on('shown.bs.collapse', function() {
$(this).parent().find(".fa-chevron-right").removeClass("fa-chevron-right").addClass("fa-chevron-down");
$(this).parent().find('.panel-heading').css('background', '#0271BC');
}).on('hidden.bs.collapse', function() {
$(this).parent().find(".fa-chevron-down").removeClass("fa-chevron-down").addClass("fa-chevron-right");
$(this).parent().find('.panel-heading').css('background', '#02A4EF');

I prefer to use examples form the Bootstrap documentation and toggle icons by CSS.
And I've added Font Awesome icons as a content of the :after pseudo-element.
Based on the Accordion example.

One of the issues with your code is that you are nesting div's in anchor (<a/>) tags. That is not allowed.

Here's a simple example, with this, initially show the icons correctly using Jquery and Bootstrap.
¡May it be very helpful to you!
