Droppable: using an "Async" accept callback

Droppable: using an "Async" accept callback

Hi,

I need to use an async function as the "accept" option when setting up a droppable().
Business-wise, I have no idea if the drop is acceptable until I check some stuff back in the server.

So, quick question: Has anyone hacked this? How, where?

Codewise, I would need to do something like this:

$("#myContainer")droppable( { accept:function( callback ){
  // some calls to the server that will eventually call the following
  callback( true )
 } } )

Thanks!
A
