/* pages/accordion/accordion.wxss */
.tui-accordion-content{
 margin: 10px;
 border: 1px solid #c8c7cc;
 border-radius: 5px;
 overflow: hidden;
}
.tui-accordion-from{padding-left: 0;}
.tui-accordion-from input{

}

.tui-input-name{

 width: 200rpx;
}

JS

var banner = require("../../src/js/banner.js");

Page({
 data: {
  isShowFrom1: false,
  isShowFrom2: false,
  isShowFrom3: false,
  indicatorDots: true,
  vertical: false,
  autoplay: true,
  interval: 3000,
  duration: 800,
  banner_url: banner.bannerList
 },
 onLoad: function (options) {

 },
 showFrom(e){
  var param = e.target.dataset.param; 
  this.setData({ 
   isShowFrom1: param == 1 ? (this.data.isShowFrom1 ? false : true) : false,
   isShowFrom2: param == 2 ? (this.data.isShowFrom2 ? false : true) : false,
   isShowFrom3: param == 3 ? (this.data.isShowFrom3 ? false : true) : false
  });
 }
})

Summary:

1 Each folding panel needs a Boolean variable to control;

2 When controlling the hiding and display of details, the arrow on the right must be switched accordingly;
3 showFrom The function optimizes the modified ternary expression for each Boolean variable.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
