I'm ok at PHP, but something of a newbie/example adapter when it comes to js and Ajax.
A while back I developed a standard web application using PHP, Prototype & Scriptaculous whereby a user could drag an item from list 1 and drop to list 2, and could also drag to resequence multiple items within list 2. Items could also be returned to list 1, with list 2 automatically re-indexing to compensate for the removed item. I used crude Ajax with PHP to keep a MySQL db in sync with the relative positions/sequence of the items.
The app lends itself to a mobile/tablet format, so I'd really like to try out converting or re-developing using Sencha Touch. Is this combination of drag, drop & sort (& Ajax) possible?
