Does anyone have any suggestions on creating dropdown lists other than using
Data Validation. I'm creating a checklist in Excel and I want to control what
users enter and also do some conditional formatting (i.e. select completed,
the cell goes green, overdue, the cell turns red).

I expect to have about 20 items to track and for each one the options will
be different. The reason I don't want to use Data Validation is that I want
to publish this to Sharepoint and Sharepoint Excel web part services do not
support Data Validation.

Would appreciate any suggestions. Thanks!
