In this article, I will show you jQuery to expand and collapse div in bootstrap accordion. You can use show and hide properties to toggle the each panel visibility.

The jQuery accordion allows you to expand and collapse div. Here I write the code to expand and collapse all panels using jQuery.

<html>

    <script type="text/javascript">
        $(document).ready(function () {
            //collapsible panel jquery expand all
            var active = true;
            $('#btnParent').click(function () {
                if (active) {
                    active = false;
                    $('.panel-collapse').collapse('show');
                    $('.panel-title').attr('data-toggle', '');
                    $(this).text('Enable accordion behavior');
                } else {
                    active = true;
                    $('.panel-collapse').collapse('hide');
                    $('.panel-title').attr('data-toggle', 'collapse');
                    $(this).text('Disable accordion behavior');
                }
            });
            $('#accordion').on('show.bs.collapse', function () {
                if (active) $('#accordion.in').collapse('hide');
            });
        });
    </script>
</head>
<body>
    <div class="container">
        <h2>collapsible panel jquery expand all</h2>
        <button id="btnParent" class="btn btn-primary">
