I have a timelines in my project with a lot of <li>. In the timeline we can add new stuff, so I don't know exacly how much <li> there will be so to use draggable I'm going through class and not by ID.

The thing is, when I do a drag to change positions between two listed items, I want to know which ones changed so next time when I reload the timeline the change will be already available in database and it will load in the correct order.

Basicly, I want to use draggable to rearrange my listed positions, but I don't know after how to get the elements rearranged. Is it possible to know? And if yes, how? 

Best Regards
