Callbacks - daneWilliams/jquery.dropdown GitHub Wiki
Almost every action performed by the dropdown is preceded and followed by a callback event, allowing for modifications to the dropdown behaviour and integration with other scripts.
Each event has a corresponding :before event which occurs before the event takes place, for example, dropdown.open:before.
