Example explanation of jquery implementation of folding menu effect

This article mainly introduces examples of jquery realizing the folding menu effect, which has a good reference value. Let's take a look with the editor below, I hope it can help everyone.

This is a simple implementation of the folding box effect. The core content is the slideToggle() method in the jQ library.

The effect is as follows:

css code:

  .con_ul{

  padding: 0;
  margin: 0;
  overflow: auto;
  }
  .con_ul li{
  list-style: none;
  padding: 10px;
  margin: 0;
  border-bottom: 1px solid #CCCCCC;
  }
  .con_ul li .title{
  padding-right: 20px;
  background-image: url(images/drop_1fcaf417.png);//默认的背景
  background-position: 100% 0px;
  background-repeat: no-repeat;
  }
  .con_ul li .title.act{
  padding-right: 20px;
  background-image: url(images/top.png);//展开后的背景
  background-position: 100% 0px;
  background-repeat: no-repeat;
  }
  .con{
  background-color: #F4F4F4;
  display: none;//内容本分默认隐藏
  padding: 5px;
  margin: 10px 0;
  }

html code: using ul li layout, I think the code structure is more concise and clear
