推荐答案

您需要的代码是：

HTML：

<nav id="main_nav">
    <ul>
      <li>
        <a href="">Dropdown</a>
          <ul>
            <li>
              <a href="">example</a>
              <ul>
                <li><a href="">example1</a></li>
                <li><a href="">example2</a></li>
                <li><a href="">example3</a></li>
              </ul>
            </li>
          </ul>
        </li>
      </ul>
</nav>

CSS：

        margin: 0;
        padding: 0;
    }

        background: #333;
        margin: 15px;
    }

    article {
        width: 600px;
        margin: 0 auto;
        background: #000;
        color: #fff;
        border-radius: 5px;
        box-shadow: 0 0 15px 2px #666;
    }

    section {
        clear: left;
    }

    h1 {
        font-size: 45px;
        font-weight: 100;
        letter-spacing: 15px;
        text-align: center;
    }

    h1, #main_content, #dog_link {
        padding: 15px;
    }

    p {
        margin: 15px 0;
    }

    a {
        color: #06c;
    }

    #main_nav ul {
        background: white;
        float: left;
        -webkit-transition: .5s;
        transition: .5s;
    }

    #main_nav li {
        float: left;
        position: relative;
        width: 150px;
        list-style: none;
        -webkit-transition: .5s;
        transition: .5s;
    }

    #main_nav > ul > li > a, h1 {
        text-transform: uppercase;
    }

    #main_nav a {
        display: block;
        text-decoration: none;
        padding: 5px 15px;
        color: #000;
    }

    #main_nav ul ul {
        position: absolute;
        left: 0;
        top: 100%;
        visibility: hidden;
        opacity: 0;
    }

    #main_nav ul ul ul {
        left: 100%;
        top: 0;
    }

    #main_nav li:hover, #main_nav li:hover li {
        background: #ddd;
    }

    #main_nav li li:hover, #main_nav li li:hover li {
        background: #bbb;
    }

    #main_nav li li li:hover {
        background: #999;
    }

    #main_nav li:hover > ul {
        visibility: visible;
        opacity: 1;
    }
