This page contains two examples of connected jQuery UI sortable lists.

On the tested browsers*, example #1 exhibits an undesirable side-effect whereby items dragged from one list to another become invisible until they're dropped. It seems to be to-do with the CSS "overflow" attribute. Example #2 shows the desired behaviour by disabling overflow.

Example #1

Drag "out li 1" across to the "in" list to see the problem. You must be using one of the tested problematic browsers* to see the problem.

#in li 1
#in li 2
#in li 3

#out li 1
#out li 2
#out li 3

Example #2

Drag "out li 1" across to the "in" list to see the desired behaviour.

#in li 1
#in li 2
#in li 3

#out li 1
#out li 2
#out li 3
