<el-form-item label="期望工作地点"
                        prop="HopeJobProvinces"
                        class="HopeJobProvincesss">
            <el-cascader style="width:200px"
                         :options="areaSelectData"
                         :props="areaSelectDataProps"
                         ref="areaSelectDataRef"
                         class="full-width"
                         size="large"
                         v-model="objectiveForm.HopeJobProvinces"
                         placeholder="期望工作地" />
          </el-form-item>

js(在data里面)

 data () {
    return {
	      // 期望工作地
	      areaSelectData: regionData, // options绑定的数据就是引入的 provinceAndCityData
	      areaSelectDataProps: { multiple: true, checkStrictly: true, multipleLimit: 3, children: 'children', value: 'value', lable: 'lable' },
	      objectiveForm：{
			      HopeJobProvinces:""
			}
         }
      }

css(如果没效果就把scoped去掉，或者在前面加上::v-deep)

.el-cascader-panel {
  .el-scrollbar:first-child {
    .el-checkbox {
      display: none;
    }
  }
  .el-scrollbar:nth-child(2) {
    .el-checkbox {
      display: none;
    }
  }
}
