From: Mike Sherov Date: Fri, 22 Aug 2014 19:16:41 +0000 (-0400) Subject: Draggable: No cloning in connectToSortable and ensure correct position X-Git-Tag: 1.11.2~33 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=95546c5d045f8055b121f24d3e35468e2a570c1b;p=jquery-ui.git Draggable: No cloning in connectToSortable and ensure correct position Draggables now forcefully recalculate their position when dragged out of a sortable. Sortables now override draggable position when a draggable is dragged into it. Lastly, no longer remove sortable helper when dragging a draggable out, which allows us to not use a clone.
