can the collapse panel in elementUI give the binding event corresponding to each el-collapse-item? I want to get some properties corresponding to item when it is expanded
< el-collapse
style= "width: 400px
<el-collapse-item
v-for="(apply,index) in applyMessageList"
:key="index">
<template slot="title">
<div @click="messageCollapseChangeEvent(apply)">//el-collapse-item
<span class="tip tipNormal"></span>
<span class="tit isNormal"></span>
<span class="time isNormal">{{apply.created_at}}</span>
</div>
<divtyle="padding: 0px 35px 0 22px">cbcvbcc"b"c"v"b"c</div>
</el-collapse-item>< / el-collapse >
solve!
