Can someone give me advice for below functionality is possible with jquery full calendar.

Once we drop a external event in to a date block, is it possible to extant the event by using a external date picker?

Eg:

1. Dropped a event in to 02 May 2014.
2. If user click on the event, a popup will show jquery Ui date picker.
3. If user select the date to 05 may 2014, the event also should extend automatically to 5th.
