Dropbox app now offers offline mode


With mobile offline folders, you can tag an entire folder to have its contents automatically synced to your phone or tablet--no need to mark individual files for download. Just open Dropbox while you're connected to the internet, and the app will take care of the rest. So whether you're on the go or off the grid, you'll always have access to your most important info.

This seems to work like selective sync on the desktop. This is a nice feature for Pro, Business, and Enterprise customers.
