Matt Warden noted: >>Thus, the two options are: >>1) List only valid values (i.e., apple, orange) >>2) List valid values (i.e., apple, orange) and one invalid >>value (i.e., Select Fruit), which is selected by default. Hi Matt, I'm pretty sure I have also seen folks use multiple invalid values. [Used for creating groups of related values.] E.g.: *Select Instrument* **Strings** - Violin - Viola **Woodwinds** - Oboe - Bassoon **Brass** - Trumpet - Euphonium Yes, this would probably be better structured as a set of paired/linked controls, (Select 'Instrument Family' -> then Select 'Instrument'), but sometimes you see it done this way. Country lists broken with headers by region - that kind of thing. RonL.
