## 批量新增栏目
View： 1. 在index.html / add.html / edit.html 的顶部添加[批量添加分类]的操作按钮
> \themes\admin_simpleboot3\portal\admin_category\index.html
> \themes\admin_simpleboot3\portal\admin_category\add.html
> \themes\admin_simpleboot3\portal\admin_category\edit.html
<ul class="nav nav-tabs">
<li class="active"><a href="{:url('AdminCategory/index')}">分类管理</a></li>
<li><a href="{:url('AdminCategory/add')}">添加分类</a></li>
<li><a href="{:url('AdminCategory/addMore')}">批量添加分类</a></li>
</ul>
2. 当前路径新增模板页 add_more.html 主要是把input改成 textarea ; 去掉别名和图片(批量新增不好处理)；表单提交到addPostMore 处理
<include file="public@header"/>
