Drag and Drop between two forms

Hi. I’ve just found DHTMLXcalendar solution. That’s really cool. But I want to add a feature. I want to create two types of tasks- one with time and another without time. You can find analogous in Google calendar. There are events and tasks. But I want a user to be able drag between those two forms. Which functions I should modify to achieve this effect?
Thank you in advance!

usually this functionality is implemented as a list of ‘todo’ items (without date) aside of dhtmlxScheduler - and items can be dragged between scheduler and this list.
