elementUI 自定义下拉选择框展示单选框、银行图片及文字等选项

最近遇到一个需求，如下图，如果用下拉框实现的话，没有插槽可用，就换了个方案，用饿了么组件库中的下拉菜单组合一个输入框来实现。

<template>
  <div class="component-wrap">
    <el-form ref="form" :model="form" label-width="80px">
      <section style="display: flex; align-items: center; margin-bottom: 20px">
        <label for="form.bank" style="width: 170px"
          >收款账号开户银行查询:</label
        >
        <el-dropdown trigger="click" placement="bottom-start">
          <el-input placeholder="请选择收款账号开户银行" v-model="form.bank">
            <i slot="suffix" class="el-icon-arrow-down"></i>
          </el-input>
          <el-dropdown-menu slot="dropdown" class="dropdown-container">
            <el-dropdown-item>
              <span
                type="info"
                style="
                  background: #f2f3f8;
                  border-radius: 32px;
                  color: #3171f6;
                  padding: 6px 10px;
                "
                @click="handleItem"

              >

只是展示页面，纯静态数据，如果用到真实项目中，大家需要请求后台数据即可。有一些小的优化，比如悬停时候的效果，大家自行处理哈，此处就不再赘述了。
图片的话，大家还需要吗？需要的话，可以给我留言哈
