效果图如下：
使用方法
<!-- flist:第一级数组 slist：第二级数组 tlist：第三级数组 @click：点击事件 注意：下一级pid与上一级id对应关联 -->
<cc-categorizeView :flist="flist" :slist="slist" :tlist="tlist" @click="navToList"></cc-categorizeView>
HTML代码部分
<template>
<view class="content">
<!-- flist:第一级数组 slist：第二级数组 tlist：第三级数组 @click：点击事件 注意：下一级pid与上一级id对应关联 -->
<cc-categorizeView :flist="flist" :slist="slist" :tlist="tlist" @click="navToList"></cc-categorizeView>
</view>
</template>
