Removing items from combo box

[SicNeMeSiS]

Hello,

I was wondering if there was a good way to remove items from a combo box after hitting a submit button. Basically I have a list box that holds steps or tasks from a checklist and as those steps are completed id like to have them disappear. My first idea was to change the fore color to match the back color but i beleive that would change all the steps in the list rather then 1 at a time. i was wondering if there was a way to have it change 1 at a time as the submit button is clicked or if there was another way i could mask the step as complete. thank you.

You may be able to set it up as a variation of a cascading combo box.
