Get global index when dragging across grouped list

[Quadx117]

Hi, I would like to know if it's possible to get the global index of the draged element when dragging across a group.

In our case, we have a table with multiple tbody. The Sortable is instanciated on each tbody and they are grouped so that we can drag across all of the tbody which are part of the same table. Everything is fine, except that when we retreive the evt,newindex it is relative to the current tbody, but we need it to be relative to the whole table instead.

For those wondering, the reason why we have multiple tbody inside the table is that each one represent a group and start with a header which is the name of that group (similiar to the contact list in outlook when grouping).

Thanks.
