is true
 * scroll-direction: <string> define scroll direction of component, horizontal 
or vertical
+  * `scroll-direction` defines the scrollable axis of scroller and 
`flex-direction` defines the layout axis of scroller. `scroll-direction` and 
`flex-direction` must be set to the same direction, otherwise, undefined 
behavior may happen.
+  * Default value for `scroll-direction` is vertical, and for `flex-direction` 
is row .

horizontal layout and scrollable scroller is expected.
+  * Use `scroll-direction:vertical` and `flex-direction: column` when a 
vertical layout and scrollable scroller is expected. But thoes two values are 
default, if you don't set them, it also works fine.
 * loadmoreoffset : <number> default value is 0. The loadmore event will be 
triggered when the list is loadmoreoffset left to reach the bottom of the list 
view. e.g. a list has total content length of 1000, and the loadmoreoffset is 
set to 400, the loadmore event will be triggered when 600 has beed scrolled and 
there is less than 400 left.
 * loadmoreretry : <number> default value 0，whether to reset loadmore related 
UI when loadmore failed, will be deprecated in further release.
