Combo box alternative to meet filesize max

Hello. I need to make a banner with a bit of functionallity to it. Right now I’m using a combo box to select from a series of choices, but the combobox component adds about 20 k to my swf. I only have 30 to work with so this leaves me very little for anything else.

Can anyone point me to a combo box alternative that does take up as many kbs?
