Muuri creates responsive, sortable, filterable and draggable grid layouts with lots of features in one library. Comparing to what's out there Muuri is a combination of Packery, Masonry, Isotope and jQuery UI sortable.
Muuri's layout system allows positioning the grid items within the container in pretty much any way imaginable. The default "First Fit" bin packing layout algorithm generates similar layouts as Packery and Masonry. The implementation is heavily based on the "maxrects" approach as described by Jukka Jylänki in his research A Thousand Ways to Pack the Bin. However, you can also provide your own layout algorithm to position the items in any way you want.
Drag & drop
Built-in support for dragging and dropping the grid items powered by Hammer.js. The drag and drop stuff is completely optional and Hammer.js is not required as a dependency if you are not using the drag and drop feature.
Simple and powerful API
Simple API with enough methods and events to gain full control over the library's behaviour. For example custom filtering and sorting of the grid items can be implemented easily (check the source of this site for starters).
Fast and highly customizable positioning and show/hide animations powered by Velocity.js.
Good browser support
Works in all modern browsers and IE9+.
