I seem to be very good at creating ghost town posts on this forum but thought I'd have one last attempt.
There is very minimal documentation out there on SS3 Grid Fields at the moment. I am looking for a way to achieve drag and drop (or another method) reordering of the items in a Grid Field. Using the dataobjectmanager in SS2.4 I just had to add SortableDataObject::add_sortable_class('Classname') to my config file and hey presto, I could order the items.
Does anyone know how I can achieve this with Grid Fields in SS3?
