	 * @property {String} btn-text = [] 底部按钮确认的文字
	 * @property {String} btn-color = [primary|green|orange|red|blue|bg-gradient-blue-lighten] 默认：bg-gradient-blue-lighten底部按钮确认的背景颜色仅支持主题色名称
	 * @property {Array} default-value = [] 默认：[],默认赋值项。可选三种赋值方式，名称赋值，对象赋值，数字序列赋值
	 * @property {String|Number} item-height = [34|42|50|58|62] 项目的高度单位px
	 * @property {Array} list = [] 选择器的数据，可选格式：Array<string>,Array<object>.如果为object格式需要提供rangKey.如果为多级需要提供children.key值
	 * @property {String} rang-key = [text|title] 默认：text,如果List格式为对象数组，需要提供此值
	 * @property {String} children-key = [children] 默认：children,如果List格式为对象数组且为多级联选择，需要提供此值，理论上无限级联数据
	 * @property {String|Boolean} black = [true|false] 是否开启暗黑模式。 
	 * @property {String|Boolean} disabled = [true|false] 是否禁用
	 * @property {String} bg-color = [white|blue] 默认：white,白色背景；请填写背景的主题色名称。
