Can an Option in a Select tag carry multiple values?

Answer 1

If you're goal is to write this information to the database, then why do you need to have a primary value and 'related' values in the value attribute? Why not just send the primary value to the database and let the relational nature of the database take care of the rest.

If you need to have multiple values in your OPTIONs, try a delimiter that isn't very common:

One

...

or add an object literal (JSON format):

One

...

It really depends on what you're trying to do.
