Pulldowns - hard to find data

Hi - I am using a pulldown to select an item. The problem is I have about 100 items (from 2 different groups). Can I change the font somehow or add something to distinguish between the 2 lists, maybe color change)???

Hi - Would it be possible to write a vb such that, if Ranges A1:A100 are in font black, and A110 to A200 are in different color in the pulldown. I'm not a big vb person.
