Best practice way to store countries and cities Is there a recommended way for storing countries and cities in craft?
I can see fields and categories as obvious options but its difficult to see the disadvantages/advantages of either at the beginning of a project.
This will depend on what you're actually trying to do, but if you're building this as part of a plugin, I'd store them as relational tables in the database, and display them as dropdown fields. If you provide more specific information about what you're building, I'll see if I can lend a hand.
