Sorting option for SpringGrid

[raghavmac]

react-stonecutter is an amazing package, many thanks. In addition, I thought it would have been great if it had sorting option for SpringGrid. Currently it works as per the masonry but compromises with the order (well, nothing wrong in it).

Hi sorry for the delay. I would prefer to have a new layout rather than adding a new Boolean prop. Just a question of what to call it, perhaps "Sorted Masonry"?

Initially, I thought the same but it will be having almost all the logic from pinterest layout except one small calculation, thus went for a prop.
