-  * Subsection 分段器
 
-  * @description 该分段器一般用于用户从几个选项中选择某一个的场景
 
-  * @tutorial https://ijry.github.io/uview-plus/components/subsection.html
 
-  * @property {Array}			list			tab的数据
 
-  * @property {String | Number}	current			当前活动的tab的index(默认 0 )
 
-  * @property {String}			activeColor		激活时的颜色(默认 '#3c9cff' )
 
-  * @property {String}			inactiveColor	未激活时的颜色(默认 '#303133' )
 
-  * @property {String}			mode			模式选择,mode=button为按钮形式,mode=subsection时为分段模式(默认 'button' )
 
-  * @property {String | Number}	fontSize		字体大小,单位px(默认 12 )
 
-  * @property {Boolean}			bold			激活选项的字体是否加粗(默认 true )
 
-  * @property {String}			bgColor			组件背景颜色,mode为button时有效(默认 '#eeeeef' )
 
-  * @property {Object}			customStyle		定义需要用到的外部样式
 
-  * @property {String}	        keyName	        从`list`元素对象中读取的键名(默认 'name' )
 
-  *
 
-  * @event {Function} change		分段器选项发生改变时触发  回调 index:选项的index索引值,从0开始
 
-  * @example <u-subsection :list="list" :current="curNow" @change="sectionChange"></u-subsection>
