We are facing an issue in using nested bootstrap accordions. On click of the Parent accordion Paperless Settings The child element icons are changing and vice versa is happening too. It should not happen, the inner accordion like any other normal accordion.

Javascript:
$('#accordion .collapse').on('shown.bs.collapse', function(){ $(this).parent().find(".fa-plus").removeClass("fa-plus").addClass("fa-nus"); }).on('hidden.bs.collapse', function(){ $(this).parent().find(".fa-minus").removeClass("fa-minus").addClass("fa- plus"); });
