需求，在树组件的后面添加提示框 并且跟随子节点出现
class="content dev-types" style="height:700px;padding:0px;">
<el-popover placement="right" width="" v-model="showpropfirm" ref="organization" :offset='50' :visible-arrow='false'>
<div style="text-align: right; margin: 0">
<div class="line">
<el-button size="mini" type="text" @click="showpropfirm = false">编辑el-button>
<el-button size="mini" type="text" @click="showpropfirm = false">删除el-button>
div>
<el-button size="mini" type="text" @click="showpropfirm = false">同级添加el-button>
<el-button type="primary" size="text" @click="showpropfirm = false">下级添加el-button>
div>
el-popover>
<el-tree :data="tree_data" show-checkbox @node-click='handeleree' v-popover:organization>
el-tree>
handeleree (a,b,c) {
this.showpropfirm = true
// this.$refs['organization'].doClose();
// this.$refs.organization.updatePopper()
}
只跟随树组件本身走，并不能根据节点走 绑定不到子结点上
让弹出框跟随tree 的子节点出现
你想每个树节点 都有 prope? 那你需要自定义 节点内容
