Things to look for with this sortable test:
- It should be a draggable, sortable list.
- It should display the order below the list when you release an item.
- It should still let you sort correctly if you scroll the list down a bit.
- It should not scroll for you as you drag ( that is not part of this test ).
- It should keep the radio selected when it is dropped.
- It should accept dragOptions limiting draggability to the y axis.
- It should detach and reattach
- It should not introduce new instances of sortables on attaching ( as exemplified by duplicates in "order" )
