Add extended dragging functionality with droppable option. Data can be attached to the element in order to specify its duration when dropped. A Duration-ish value can be provided. This can either be done via jQuery or via an data-duration attribute. This option operates with jQuery UI draggables. You must downloadthe appropriate jQuery UI files and initialize a draggableelement. Additionally, you must set the calendar's droppableoption to true.

Allows a user to highlight multiple days or timeslots by clicking and dragging. To let the user make selections by clicking and dragging, selectableoption must be set to true. The selectand unselectcallbacks will be useful for monitoring when selections are made and cleared.
