Highlight values in combobox

[Gannet]

Is it possible to highlight rows of a combobox based on a hidden boolean value in the second column? I've tried using the code [combobox].column(1)=1 under conditional formatting with no luck. I'm including a photoshoped image of what I want.

not with an existing control. You would need a custom control designed and installed and then installed on each computer.

or use a listbox; you can select multiple fields manually or programatically.

Thanks for the suggestions.
A list box won't work very well because of space issues but I think I'm just going to show the second column to indicate which ones are checked. I was hoping for something a little more stylish but this other way will work fine.
