Hiệu ứng accordion giúp một vùng liên kết được kích chuột vào có thể xếp lại trông giống như đàn accordion. Sử dụng hiệu ứng này với sự hỗ trợ của Mootools có thể tạo một thanh menu dọc khá ấn tượng.
Xem Demo.
Sau đây là hướng dẫn cài đặt hiệu ứng:
Bước 1: Trước tiên, bạn hãy đặt toàn bộ phần code bên dưới vào phần đầu của trang HTML, nằm giữa 2 thẻ <head>, </head>.

Bước 3: Đặt đoạn code sau đây trước thẻ đóng </body>.
<script type="text/javascript" src="http://www.ryanscherf.net/demos/accordion/accordion.js"></script>
Chú ý ở Bước 2, bạn phải tùy chỉnh scr theo URL các file hình ảnh tương ứng của bạn.
Hiệu ứng này có thể áp dụng cho Blogger khá dễ dàng.
