Question

我正在尝试构建一个导航栏，其中子菜单使用css从页面侧面滑入。我遇到的问题是当子菜单滑动时父菜单项的位置发生变化。我在这里做了一个小提琴http://jsfiddle.net/CL7d7/可以有人建议我哪里出错了。

HTML

            <ul>
                <li><a href="#">Home</a></li>
                <li>
                    <a class="box" href="#">Weddings</a>
                      <ul>
                        <li><a href="#">one</a></li>
                        <li><a href="#">two</a></li>
                        <li><a href="#">three</a></li>
                    </ul>                       
                </li>
                <li><a href="#">Biography</a></li>
                <li><a href="#">Services</a></li>
                <li><a href="#">Photobooth</a></li>

            </ul>



        </div><!-- end #nav -->

CSS

#wrap{

   width:500px;
   overflow: hidden;    
  }

 #nav {

right: -500px;
position: absolute;

    }

   #nav ul ul li {

   }
  #nav ul ul a  {

height: 35px;
  }
  #nav ul ul a:hover {

  }

   #nav ul li:hover > ul {

    }

    #nav ul ul li {

    }
    #nav ul ul a  {
color: #F9C;
font-size: 12px;
width: 80px;
height: 35px;
    }
    #nav ul ul a:hover {
display: block;
color: #99999;
font-size: 12px;
position: absolute;

     }

    #nav ul li:hover > ul {
overflow: hidden;
right: 0px;
display: block;
top: 0px;
position: relative;


     }

     #nav li:hover > a {
color: #99999;
display: block;
     }




     #nav li:hover > a {
color: #99999;
display: block;
      }

Answer 1

在#nav ul li:hover > ul中将您的定位更改为绝对。同时设置顶部属性以进行对齐。

应该是这样的：

#nav ul li:hover > ul {
    overflow: hidden;
    right: 0px;
    display: block;
    top: 40px;
    position: absolute; 
}
