最近项目需求要做工作流组件，没办法这种东西还得插件好用，不过样式调的我头皮发麻，所以把代码放博客上，喜欢的就点赞吧！

先安装插件

npm install workflow-ui --save

<template>
  <div class="work-flow">
    <div class="fd-nav-content">
      <div
        class="dingflow-design"

        <div class="ie-polyfill-container">
          <div
            class="box-scale"
            style="transform: scale(1); transform-origin: 50% 0px 0px;"
          >
            <Node
              v-for="(item, index) in items"
              :key="index"
