Question

所以我想创建一个菜单，当悬停时有一个类似于This website的滑动。任何人对我如何完成这个有任何想法？

<nav>
    <ul>
        <li>Menu 1
            <ul>
                <li>Sub 1</li>
                <li>Sub 2</li>
                <li>Sub 3</li>
            </ul>
        </li>
        <li>Menu 2</li>
        <li>Menu 3</li>
    </ul>
</nav>

    <ul class="clearfix">
        <li><a href="">Menu 1</a>
            <ul>
                <li><a href="">Sub 1</a></li>
                <li><a href="">Sub 2</a></li>
                <li><a href="">Sub 3</a></li>
              <li><a href="">Sub 1</a></li>
                <li><a href="">Sub 2</a></li>
                <li><a href="">Sub 3</a></li>
            </ul>
        </li>
        <li><a href="">Menu 2</a>
      <ul>
                <li><a href="">Sub 1</a></li>
                <li><a href="">Sub 2</a></li>
                <li><a href="">Sub 3</a></li>
            </ul>
      </li>
        <li><a href="">Menu 3</a>
      <ul>
                <li><a href="">Sub 1</a></li>
                <li><a href="">Sub 2</a></li>
                <li><a href="">Sub 3</a></li>
            </ul></li>

  z-index: 1;
