Just define which container you want it to be (#container) and item selector by class (.item) then you can get started in seconds. Quite handy script for who are looking for a quick client side sorting solution for their products, photos, data records, listing, etc.
It is free to use for any personal projects or non-profit projects not free to commercial purpose. Anyway, very appreciate to Metafizzy who created this useful filtering and sorting script. Do you like this or not?
