Đoạn mã JavaScript này sẽ tạo một trình đơn nhiều cấp trên trang web (trong ví dụ JavaScript mẫu là 3 cấp, và dĩ nhiên bạn có thể tạo bao nhiêu cấp cũng được).Điểm sáng giá của hiệu ứng JavaScript này ở chỗ nó chỉ cho phép một trình đơn cấp gốc được chọn mỗi lần; đồng thời nó dùng cookie để lưu trạng thái đóng/mở của các trình đơn, mỗi khi trang web được tải lại thì nó vẫn hiển thị vị trí đã mở.
