嘿，我有一个相当多的设计，我的下拉菜单，我有麻烦添加一个子菜单，让我们说，在下拉菜单上的第一个元素-cotent div。

我只想让子菜单从定义了子菜单的悬停位置开始，向右并以与当前子菜单相同的方式下拉。下面是我的html：

代码语言：javascript
复制
    <nav>
          <div class="main-nav">
            <ul class="left">
              <li class="dropdown"><a href="#">Home</a>
                <div class="dropdown-content">
                  <a href="#">Third</a>
                  <a href="#">Third Link</a>
                  <a href="#">Third Link 3</a>
                </div>
              </li>
              <li><a href="#">Gods</a></li>
              <li><a href="#">Goddesses</a></li>
            </ul>
            <div class="play-now"></div>
            <ul class="right">
              <li><a href="#">Heroes</a></li>
              <li><a href="#">Myths</a></li>
              <li><a href="#">Beasts</a></li>
            </ul>
          </div>
        </nav>

下面是所有内容的css：

代码语言：javascript
复制
nav {
    padding-left: 5px
}

nav .main-nav {
    height: 80px;
    width: 100%;
    margin-top: 64px;
    background: url(../images/navHeader.png) no-repeat top;
    position: relative
}

nav .main-nav ul {
    width: 360px;
    height: 80px;
    margin-top: 2px;
    padding: 0;
    list-style-type: none
}

nav .main-nav ul a,
nav .main-nav ul li {
    display: inline-block;
    width: 105px;
    line-height: 80px;
    height: 80px

}

nav .main-nav .dropdown-content a {
  height: auto;
  line-height: initial;
  padding: 3px 0;
}

nav .main-nav ul a {
    text-align: center;
    font-weight: 550;
    font-size: 12px;
    color: #84827d;
    text-shadow: 1px 1px 1px 1px #000;
    text-transform: uppercase;
    -webkit-transition: all .2s ease-in-out;
    transition: all .2s ease-in-out
}

nav .main-nav ul a:hover {
    text-decoration: none;
    color: #7289da
}
nav .main-nav li .dropdown {

}
nav .main-nav .dropdown-content {
    position: absolute;
    display: none;
    float: left;
    z-index: 10;
    -webkit-box-shadow: 0 3px 5px 0 #999;
    -moz-box-shadow: 0 3px 5px 0 #999;
    box-shadow: 0 3px 5px 0 #999;
    border: 1px solid #CCC;
    background: #3A4FC5;
    color: #656161;
    opacity: .8;
    min-width: 30px;
    top: 60px;
}

nav .main-nav .dropdown-content a {
    color: black;
    text-decoration: none;
    display: block;
    text-align: center;
}
nav .main-nav .dropdown-content a:hover {
    background-color: #3A4FC5
}

nav .main-nav .dropdown:hover .dropdown-content {
    display: inline-block;
}

nav .main-nav ul.left {
    float: left;
    margin-left: 5px;
}

nav .main-nav ul.right {
    float: right;
