@protocol DropDownMenuListDataSouce <NSObject>
@required
// 设置显示列的内容
-(NSMutableArray *)menuNumberOfRowInColumn;
// 设置多少行显示
-(NSInteger)menu:(DropDownMenuList *)menu numberOfRowsInColum:(NSInteger)column;
// 设置显示没行的内容
-(NSString *)menu:(DropDownMenuList *)menu titleForRowAtIndexPath:(HZIndexPath *)indexPath;

@optional
// 每行图片
-(NSString *)menu:(DropDownMenuList *)menu imageNameForRowAtIndexPath:(HZIndexPath *)indexPath;

@end

@protocol DropDownMenuListDelegate <NSObject>
@optional
// 点击每一行的效果
- (void)menu:(DropDownMenuList *)segment didSelectRowAtIndexPath:(HZIndexPath *)indexPath;
// 点击没一列的效果
- (void)menu:(DropDownMenuList *)segment didSelectTitleAtColumn:(NSInteger)column;
