element select改成成tree树状下拉

<template><el-select class="jhx-formData-inputRow" ref="configSelect" v-model="orgName" filterable placeholder="请选择":filter-method="filterMethod" clear><el-option :label="orgValue.label" :value="orgValue.value" style="height: auto; display: none"></el-option><el-input placeholder="输入关键字进行过滤" style="width:92%;margin-left:3%;margin-top:10px" v-model="filterText"></el-input><el-tree ref="orgTree" :data="orgList" :props="orgDefaultProps" @node-click="handleorgDodeClick":filter-node-method="orgFilterNode" :default-expand-all="true"></el-tree></el-select>
</template>
