树形侧边栏（展开、全选、切换名称）

本文主要是介绍树形侧边栏（展开、全选、切换名称），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

父文件： index.vue

<template><div class="h-full p20px bg-#f5f5f5"><ContentWrap class="w-260px h-[calc(100vh-200px)] min-h-700px"><TenantTree @select="tentantSelect" /></ContentWrap></div>

const mutData = ref<String>('')
const tentantSelect = (data) => {mutData.value = data?.join(',')
