Dropdown default value - set to blank value?

[dfin]

I have an edit screen with two dropdowns controls.  The first dropdown is Client and the sceond is ClientProject.  After choosing the client, the user can seleect the specific project for the client.  The ClientProject dropdown is filtering it's list values based on the value of the Client dropdown.

When adding a new record, though, after I select a client, the Client Project dropdown always gets set to the first value on the list.  I would preer that it would be left blank.  Is this possible?

Thanks,

Dave

Using the combo box worked perfectly for me! Thanks, @Jeff_Thorpe.
