Removing scrollbar in selectlist????

Is it possible to remove the scrollbar in a selectlist??
and if so, how do I do that??

Thanks in advance !

The question is why? How many items are you displaying? The only reason you should get a scroll bar is if there are more items then can be displayed and if you remove the scroll bar in this situation there would be no way to get to the hidden items.

well, the number of items is 5 and I've set the size of the selectlist also to 5, normally the scroll should just be hidden, but it isn't.
So, how can I solve this problem??
