本文实例为大家分享了vuedraggable实现嵌套多层拖拽排序功能的具体代码，供大家参考，具体内容如下
vue中实现嵌套多层拖拽功能。官网入口：
实现效果：（拖动左侧调整一级的顺序，拖动右侧调整二级的顺序）
实现步骤：
***这里使用了插件 vuedraggable
第一步：安装插件
cnpm install vuedraggable --save第二步：在页面上引入插件并注册
import draggable from 'vuedraggable'
components: {
draggable
},第三步：页面上使用
<template>
<div class="wholeList">
<draggable
class="leftCon"
:list="tolList"
>
<div class="leftConLi" v-for="element in tolList" :key="element.id">
{{ element.name }}
</div>
</draggable>
<ul class="oneUl">
<li
class="oneLi"
v-for="(item,index) in tolList"
:key="index"
>
<!--拖拽内容部分-1-->
<draggable
v-if="index === 0"
class="dragArea list-group"
:list="item.children"
:clone="clone"
:group="{ name: 'people', pull: pullFunction }"
@start="start"
>
<div v-for="element in item.children" :key="element.id" class="list-group-item">
{{ element.name }}
</div>
</draggable>
<!--拖拽内容部分-其他-->
<draggable
v-else
class="dragArea list-group"
:list="item.children"
:clone="clone"
group="people"
>
<div v-for="element in item.children" :key="element.id" class="list-group-item">
{{ element.name }}
</div>
</draggable>
</li>
</ul>
<el-button @click="getNewList">点我看console里面的最新数据</el-button>
</div>
</template>
