Is there a way to filter an enumerated list based on the selection of
another enumerated list? For example enum1 has Red, White, Blue as
its values. Enum2 has Red 1, Red 2, Red 3, White 1, White 2, White
3, Blue 1, etc. When I select a value from Enum1 I want Enum2 to
filter the choices accordingly. E.g., if I select Red in enum1, I
would expect to see only the values Red 1, Red 2, and Red 3 in enum2.
