心情有点烦躁，直接上码吧…

npm i -S vuedraggable    
//首先先装一下vuedraggable
import draggable from "vuedraggable"
export default{
	data(){
		return{
			materialsList:[]
		}
	},
	components:{
		draggable
	},
	methods:{
		change(){},
		start(){},
		end(){},
		move(){}
	}
}

<template>
	    <draggable
        	class="draggable"
            v-model="materialsList"
            @change="change"
            @start="start"
            @end="end"
            @move="move"
            >
              <li v-for="(item,index) in materialsList" :key="item.name" class="materials-li"></li>
        </draggable>
</template>
