本文实例为大家分享了vue实现手风琴效果的具体代码，供大家参考，具体内容如下
利用鼠标移入移出事件实现内容出现隐藏
用到的知识点：
1.@mouseover 鼠标移入事件
2.@mouseout 鼠标移出事件
3.v-if 条件渲染
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<!-- 简单样式设置 -->
<style type="text/css">
* {
margin: 0;
padding: 0;
}
ul {
list-style: none;
}
.title{
width: 90px;
height: 40px;
line-height: 40px;
text-align: center;
background-color: #AFAFAF;
}
.active{
background-color: #000000;
color: white;
}
</style>

<div id="box">
<ul class="ul">
<!-- 鼠标移入移出事件 -->

<!-- 条件渲染 -->
