document.addEventListener('DOMContentLoaded', function () {

    document.querySelectorAll('.offcanvas-inner .offcanvas-menu-toggler').forEach(function (toggler) {

        // Prevent Bootstrap from handling the same click
        toggler.removeAttribute('data-bs-toggle');

        toggler.addEventListener('click', function (e) {
            e.preventDefault();
            e.stopPropagation();

            var targetSelector = toggler.getAttribute('data-bs-target');

            if (!targetSelector) {
                return;
            }

            var target = document.querySelector(targetSelector);

            if (!target) {
                return;
            }

            var isOpen = target.classList.contains('show');

            if (isOpen) {
                // Collapse
                target.classList.remove('show');
                toggler.classList.add('collapsed');
                toggler.setAttribute('aria-expanded', 'false');
            } else {
                // Expand
                target.classList.add('show');
                toggler.classList.remove('collapsed');
                toggler.setAttribute('aria-expanded', 'true');
            }
