Actionscript 3 :: Wrap Lists Into Columns?

How do you make a List control wrap around to a second column (or multiple columns)? let me know if there is a solution for this with the List control or some other Flex control.

For example, if you have one list with 42 items in it, but I want to cap the height of a list to 20 items; then instead of having one list with 42 items all the way down, I would have that list of items look like the equivalent of 3 adjacent lists: the first with 20 items, the second with 20 items, and the third with 2 items (which represent the original list of 42 items).
