Ok, look at that code:
| collection1 collection2 list1 list2 |
collection1 := #(1 2 3 4 5) asOrderedCollection.
collection2 := #($a $b $c $d $e) asOrderedCollection.
list1 := ListModel new.
list1 items: collection1.
list1 dragEnabled: true.
list1 dropEnabled: true.
list1 acceptDropBlock:
[ :transfer :event :source :receiver :index |
transfer passenger do:
[:e |
collection1 insert: e first before: index.
collection2 remove: e first].
list1 items: collection1.
list2 items: collection2 ].
list1 openWithSpec.
list2 := ListModel new.
list2 items: collection2.
list2 dragEnabled: true.
list2 dropEnabled: true.
list2 acceptDropBlock: [ :transfer :event :source :receiver :index |
self halt ].
^ list2 openWithSpec
Now you can drag and drop from list2 to list1, and I think the code is
good for drag and drop of multiple items.

I tried the following, but i do not know what to do in the acceptDropBlock.
It seems the receiver in the block is only an item in a list, but how do i
get the receiving list/collection?
What i want to achieve is that a user can drag the '1' from list1 to list2
and the resulting collections will then be collection1: (2 3 4 5)
collection2: ($a $b $c $d $e 1) and the lists will be updated accordingly.

yes, most list-like widgets can drag and drop. Feedback when inserting
items in lists could be improved, however (i.e. you can drop on a list
item, but I've never seen the feedback for dropping between list items).

i have to make a UI where users can sort items (sentences) into different
collections by dragging and dropping them between list views. Is this
possible with the widgets currently available in Pharo?
