2 Selection Lists in a web form

[Jean Biver]

Dear readers:

I found a web page with 2 selection lists in a form. The contents of
the second selection list are updated based on the entry in the first
selection list. For example:
if the first selection list has all the states in the USA, the second
list will display all the major cities in the selected state.

Can anyone explain in a pseudocode how this is implemented.

Regards,
Jean Biver

It is a neat idea, but the hard part is to make it degrade nicely if
Javascript isn't available.

Can anyone explain in a pseudocode how this is implemented.
