jQuery.Shapeshift: Pinterest-Like Dynamic Grids With Drag ‘n’ Drops
jQuery.Shapeshift is a strong alternative to them with an an extra touch: the items can be drag ‘n’ dropped (uses jQuery UI).
The drag ‘n’ drop doesn’t effect the grid negatively as the grid auto-fills the gaps when needed.
It also works on touch devices and responsive layouts.
The plugin comes with lots of options to set the margins, enable/disable drag-drops, customize animation and much more.
