I want to create a field where a user can select a nearby mass transit system; so, it must be multiply levels, for example:
- Country #1:
-- City #1:
--- Transit System Name #1
---- Transit Station #1
---- Transit Station #2
--- Transit System Name #2
---- Transit Station #1
---- Transit Station #2
-- City #2:
- Country #2:
-- City #1:
--- Transit System Name #1
---- Transit Station #1
---- Transit Station #2
--- Transit System Name #2
---- Transit Station #1
---- Transit Station #2
I assume I basically follow the same procedures for entering multiple countries.
I would need two fields with the same data entries in case of the rare event that a location is near two mass transit systems.
Any advice you can share would be gratefully appreciated.
