User defined order for categories I'd like to set a user defined order for a Categories field. For example, categories are:

Cat A
Cat B
Cat C

I'd like to give the ability for users to drag and drop the order, to say:

Cat B
Cat A
Cat C

What is the best way to handle this?
I ended up finding this code snipped, which worked for me:
