How do I create a dropdown within a dropdown?

[Joyce Keller]

I know how to create a dropdown list.
On one or more of the items in that dropdown list, I would like to create
another dropdown.
How do I do this?

The second list dependent on what was chosen in the first????

If you used Data|validation for your dropdown list, then you could visit Debra
