Auto-resort numbers in selectable numbered list

/ Published in: JavaScript
Save to your folder(s)

When you have a list of items to sort (say, three items, each with a drop-down from 1-3), this script will (when one of the item drop-downs is changed) automatically change the others to have appropriate numbers. For example, if your list is numbered: 1, 2, 3...and you change the second item to 3, the list will then be numbered 1, 3, 2.
