使用vant折叠面板自定义内容

效果图：

Collapse 折叠面板

介绍

将一组内容放置在多个折叠面板中，点击面板的标题可以展开或收缩其内容。

引入

import Vue from 'vue';
import { Collapse, CollapseItem } from 'vant';
 
Vue.use(Collapse);
Vue.use(CollapseItem);

代码演示

基础用法

通过 v-model 控制展开的面板列表，activeNames 为数组格式。

<van-collapse v-model="activeNames">
  <van-collapse-item title="标题1" name="1">内容</van-collapse-item>
  <van-collapse-item title="标题2" name="2">内容</van-collapse-item>
  <van-collapse-item title="标题3" name="3">内容</van-collapse-item>
</van-collapse>

export default {
  data() {
    return {
      activeNames: ['1'],
    };
  },
};

在基础用法的基础上，因为页面太长，因此需要使用手风琴模式。

手风琴

通过 accordion 可以设置为手风琴模式，最多展开一个面板，此时 activeName 为字符串格式。

<van-collapse v-model="activeName" accordion>
  <van-collapse-item title="标题1" name="1">内容</van-collapse-item>
  <van-collapse-item title="标题2" name="2">内容</van-collapse-item>
  <van-collapse-item title="标题3" name="3">内容</van-collapse-item>
</van-collapse>

export default {
  data() {
    return {
      activeName: '1',
    };
  },
};

基于以上官方文档介绍，下面实现自己的代码逻辑。

 页面渲染：

<van-collapse v-model="activeNames" accordion>
                    <van-collapse-item :title="item.type" :name="item.type" v-for="        (item,index) in typelist" :key="index">
                        <van-form v-for="(ele,i) in item.data" :key="i">
                            <van-row gutter="20">
                                <van-col span="2">
                                    <van-field
                                        :name="i+1+''"
                                        :label="i+1"
                                    />
                                </van-col>
                                <van-col span="16">
                                    <van-field
                                        v-model="ele.name"
                                        label-width="16em"
                                        :name="ele.name"
                                        :label="ele.name"
                                    />
                                </van-col>
                                <van-col span="6">

                                        v-model="ele.unit"
                                        :name="ele.unit"
                                        :label="'单位:'+ele.unit"
                                    />
                                </van-col>
                                <van-field
