Drag/drop multiple items
Hello Sebastien,
I'm trying to implement subj.
JS example I'm using as POC is here [1]
Everything works, except for one thing: no matter how many objects I'm
dropping I only have 1 onDrop() event inside wicket ....
can you help me to fix/workaround this?
Thanks in advance!

Actually this is good question :)
- selected items are being stored on server
somehow I missed the fact I can do all processing on server
Thanks a lot for the pointer!

Hi Maxim,
Depending of your selection logic, you have 2 ways:
- a behavior based solution
- a component based solution
If you can have a wicket component holding the selection (trough its model)
then opt for a component based solution. The component will be passed to
#onDrop so its easy to retrieve the selection (because it's the component's
model). You can use the draggable "helper" to enhance the visual dnd ui
(example here [1]).
If the selection is client side only, then I think you need to deal with a
behavior based solution (no wicket component involved). Tell me if it's
your case, I can try to help out.
Best regards,
Sebastien.

Thanks for links Sebastien
Unfortunately I need custom selection logic ....
Ill try to check internals of your examples to achieve same results :)
WBR, Maxim

Hi Maxim,
The recommended way to dnd multiple items is to use: selectable + draggable
+ droppable
You have 2 examples here:
http://www.7thweb.net/wicket-jquery-ui/selectable/DraggableSelectablePage
http://www.7thweb.net/wicket-jquery-ui/selectable/TableDraggableSelectablePage
Hope this helps :)
Sebastien.

To be fair I'm not sure :(
This magic is hidden inside DroppableBehavior code :(
And I'm afraid my "drop" handler might be overridden inside
DroppableBehavior.onConfigure
Hopefully Sebastien can help here :)

Can you group them in javascript and detect group in wicket side, for
example as list of ids?
