<el-form-item label="选择算法模型：">
  <el-cascader
    v-model="formInline.algorithmId"
    :options="modelOptions"
    :props="{ value: 'id', label: 'name', multiple: true, emitPath: false,}" //后俩个重点
    filterable
    clearable
    placeholder="请选择"
    style="width: 430px;"
    @change="modelChange"
  >
    //自定义展示
    <template slot-scope="{ node, data }">
      <span>{{ data.name }}</span>
      <span v-if="!node.isLeaf">({{ data.children.length }})</span>
    </template>
  </el-cascader>
</el-form-item>


//算法模型改变
modelChange(val) {
  console.log("算法模型改变");
  console.log(val);
},

拓展：单选只取最后一级

<el-form-item label="工序">
 <el-cascader
    v-model="formInline.processId"
    :options="processOptions"
    :props="{ value: 'id', label: 'name' }"
    :show-all-levels="false" //重点
    @change="ziduanSearch"
  ></el-cascader>
</el-form-item>



//字段
ziduanSearch(val) { 
  this.formInline.processId = val[val.length - 1]; 
},
