Reorder horizontally and grid

Hi! I’m trying to do a horizontally displayed list, and i need to reorder. Vertically i don’t have any problem, but when i show the horizontal list and after that i try to reorder it, i can move the element vertically only.

After this, i’ll need to reorder a grid with pictures thumbnails and i haven’t found any information about it.

Thanks you and sorry for my english!! :wink:

Please some help needed!!

Thanks a lot!
