/**
* collapseItem 手风琴Item
* @description 通过折叠面板收纳内容区域(搭配u-collapse使用)
* @tutorial https://www.uviewui.com/components/collapse.html
* @property {String} title 面板标题
* @property {String Number} index 主要用于事件的回调,标识那个Item被点击
* @property {Boolean} disabled 面板是否可以打开或收起(默认false)
* @property {Boolean} open 设置某个面板的初始状态是否打开(默认false)
* @property {String Number} name 唯一标识符,如不设置,默认用当前collapse-item的索引值
* @property {String} align 标题的对齐方式(默认left)
* @property {Object} active-style 不显示箭头时,可以添加当前选择的collapse-item活动样式,对象形式
* @event {Function} change 某个item被打开或者收起时触发
* @example <u-collapse-item :title="item.head" v-for="(item, index) in itemList" :key="index">{{item.body}}</u-collapse-item>
