On a computer at everydollar.com:
1. Hover the mouse pointer over the budget item you want to move.
2. Click the (
) button and drag the budget item.
3. Drop it where you want it to go and you're all set!
Unfortunately, at this time, we don't have a way to move a budget item to a different category/group, since a lot of the built-in reporting is based on group distinction. You would be able to create those items with the same name in a new category if you wanted, however, the data would not transfer.
