@woxblom yeah but it's not able to do it so if you make it changes and provide features with this things in your lib then it will help for us. Your lib well understand by you so you make it changes quickly.

Yeah sorry it is a to big of a change from what the lib was designed to do so I won't implement that feature.

@woxblom if you provide some hint via code that will also helpful for me. i know your lib have limited design scope , so you just give me some hint on code so we will change in your lib code and send pull request.

The problem is that I can't really give you a good hint as it is not straight forward to add such a feature. I mean there is already a pretty complex logic about how to transfer an item between two different recyclerviews. To add more logic on top of that to also include dragging between top and bottom horizontal scrollviews will be a very complex task to add.

The only hint I can give you is to look in the BoardView class where the dragging takes place (updateScrollPosition()). There you will see that I switch the dragging item between the recyclerviews when the mTouchX changes position. You would need to add code here to also include mTouchY and to compare to top and bottom scrollviews with the recyclerviews.

I am going to be completely honest with you, I won't say that it is impossible because nothing is, but it will be a hard task to include this feature without breaking the current functionality.
