I don't work with sortables much.
Demo here has sortables within tabs. Tabs are droppables and over event triggers hovered tab to open. This trigger works using jquery 1.6.3 but not 1.7 which I can live with.
With new tab displayed user can then continue dragging the sortable into it's allowed element within new tab. This really didn't work well without using page offset for hidden tab content as placeholder kept getting width set to 0px.
System works OK but gets a little buggy when it's original page position corresponds with position in new tab. It also seems to take several over and outs to get placeholder to show on new tab sometimes
Am trying to figure out any method to force or refresh the placeholder to recognize it's position is not the same as on new tab.
Any ideas appreciated.
