bạn cần thay đổi tên menu chính và con, thay dấu "#" là các địa chỉ link mình cần liên kết đến và bấm Lưu lại là xong.
Mở rộng thêm:
Nếu muốn thêm menu phụ thì bạn copy đoạn code này:
<li><a href="#">Tên menu con </a></li>
Dán tiếp trên dòng lệnh </ul> của mỗi menu chính mà mình muốn thêm.
Còn muốn thêm một menu chính thì bạn copy đoạn code này:
<h3 class="menuheader expandable">☆Tên menu chính </h3>
<ul class="categoryitems">
<li><a href="#">Tên menu con 1</a></li>
<li><a href="#">Tên menu con 2</a></li>
<li><a href="#">Tên menu con 3</a></li>
<li><a href="#">Tên menu con 4</a></li>
</ul>
</div>
Dán trên thẻ </div> cuối cùng.
<ul class="categoryitems">
<li><a href="#">Tên menu con 1</a></li>
<li><a href="#">Tên menu con 2</a></li>
<li><a href="#">Tên menu con 3</a></li>
<li><a href="#">Tên menu con 4</a></li>
</ul>
