Scrollbar on 2010 list control

Question

I have a 2010 C# asp.net webform application that I just placed a checkboxlist control on the form. The problem is the selections that are user can make are extremely  large. Thus i am wondering if there is away to make the checkbox list control have a scroll bar?
 Can I embedded the checkboxlist control in some type of a web control? If so what would it be?
Should I just  use a regular checkbox control and put a group control are the checkboxes? Would this help anything?
