Newly appended elements do not become draggable/sortable

[Phaet]

I want to create a list of items dynamically by means of $( "#list").append(item). I noticed, though, that the items do not become sortable.
I also tried to apply $("#list").sortable() after the list creation has been completed, but this does not work either.
Is there something like .sortable('refresh') similar to what JQuery UI provides?

Found the answer myself: I tried to sort items. But sortable items need to be container elements. Embedding each img in li does the trick.

Great, thanks for your feedback :) Cheers!
