    window.addEventListener('DOMContentLoaded', (event) => {
        // listen on ajax failed, done to render items.
        document.addEventListener('rdScrollPagination.start', (ajaxEvent) => {
            const loadingHtml = '<p class="item-loading">Loading &hellip;</p>';
            document.querySelector('#posts-container').insertAdjacentHTML('beforeend', loadingHtml);
        });
        document.addEventListener('rdScrollPagination.fail', (ajaxEvent) => {
            let loadingElement = document.querySelector('.item-loading');
            if (loadingElement) {
                loadingElement.remove();
            }
        });
        document.addEventListener('rdScrollPagination.done', (ajaxEvent) => {
            let loadingElement = document.querySelector('.item-loading');
            if (loadingElement) {
                loadingElement.remove();
            }

            let response = (ajaxEvent.detail ? ajaxEvent.detail.response : {});

            let listHtml = '';
            if (response.items) {
                response.items.forEach((item, index) => {
                    listHtml += '<div class="each-post-item"><p>' + item + '</p></div>';
                });
            }

            document.querySelector('#posts-container')
                .insertAdjacentHTML('beforeend', listHtml);
        });

        // initialize new scroll pagination class.
        let scrollPaginationClass = new RundizScrollPagination({
            'containerSelector': '#posts-container',
            'childrenItemSelector': '.each-post-item',
