html - 从 sub 创建 css 子菜单

Question

你好我想要的是从子菜单创建子菜单。例如，如果用户将鼠标悬停在 Actions 上，则它会下降以显示账单 - 邮件等。如果用户将鼠标悬停在账单上，我想创建另一个子。我附上了我正在使用的代码，它是 stu nicholls pro 下拉列表。谢谢

Answer 1

尝试使用嵌套 <ul> s 在你的 HTML 中。也就是说，像这样构建您的菜单:

<ul class="menu">
  <li>
    <a>My Link</a>
    <ul class="submenu">
      <li><a>My Nested Link</a></li>
  </li>
</ul>

然后使用简单的 Javascript 解决方案，如 Superfish(或您选择的一种) http://users.tpg.com.au/j_birch/plugins/superfish/
