首先给大家展示下效果图,喜欢的朋友继续往下看哦。

这是一款简单但实用的多级垂直手风琴下拉列表菜单。该多级手风琴菜单完全使用CSS来制作,它通过将不同的子菜单进行分组,制作出多级菜单的效果。

该多级手风琴菜单通过在checkbox元素上使用:checked伪元素来制作。如果需要一些好看的动画效果,可以实用插件中提供的main.js文件,它可以提供菜单打开和收缩时左侧小箭头的动画效果。

使用方法

HTML结构

该多级手风琴菜单的HTML结构非常简单:整个手风琴是一个无序列表。如果某个列表项中包含有子菜单,则添加一个input[type=checkbox]和一个label标签,同时为该列表项添加一个.has-children的class类。所有其它标准的列表项都包含在一个a标签中。

<ul class="cd-accordion-menu">
 <li class="has-children">
 <input type="checkbox" name ="group-1" id="group-1" checked>
 <label for="group-1">Group 1</label>
 <ul>
 <li class="has-children">
  <input type="checkbox" name ="sub-group-1" id="sub-group-1">
 <label for="sub-group-1">Sub Group 1</label>
 <ul>
  <li><a href="#0">Image</a></li>
  <li><a href="#0">Image</a></li>
  <li><a href="#0">Image</a></li>
 </ul>
 </li>
 <li><a href="#0">Image</a></li>
 <li><a href="#0">Image</a></li>
 </ul>
 </li>
 <li><a href="#0">Image</a></li>
 <li><a href="#0">Image</a></li>
</ul> <!-- cd-accordion-menu --> 
Copy after login

CSS样式

该多级手风琴菜单仅使用CSS来检测点击和展开子菜单。它使用的方法是通过checkbox元素,然后通过:checked伪类和相邻的兄弟选择器来改变

    元素的显示模式,从“none”改变为“block”。

    首先需要确保所有有子菜单的列表项都带有checkbox元素。当你点击在一个label元素上的时候,实际是点击了相应的checkbox元素:这通过设置label元素的for属性来实现。接着就可以简单的隐藏checkbox元素,通过label元素来取代它。

    .cd-accordion-menu input[type=checkbox] {
     /* hide native checkbox */
     position: absolute;
     opacity: 0;
    }
    .cd-accordion-menu label, .cd-accordion-menu a {
     position: relative;
     display: block;
     padding: 18px 18px 18px 64px;
     background: #4d5158;
     box-shadow: inset 0 -1px #555960;
     color: #ffffff;
     font-size: 1.6rem;
    }  
    Copy after login

     JavaScript

    如果你需要为这个手风琴菜单添加一些好看的动画效果,可以使用jQuery和插件中提供的main.js文件。同时需要在ul.cd-accordion-menu元素上添加.animate class类,它会使小箭头的方向在打开和关闭子菜单时产生动画效果。
