Where can I find a database of European countries and related cities to implement country/city dropdown list (dynamic) in the web-page?
UPDATE: I´m interested in some database that I can utilize from the javascript or php source code. This is to avoid manual work.
My answer: I have found one more good free resource: http://www.geodatasource.com/world-cities-database
http://en.wikipedia.org/wiki/Europe#Political_geography
Wikipedia always works :)
For some reason I thought about capitals only, but I guess you mean all cities.
Take a look at: http://download.geonames.org/export/dump/
Check out the readme.txt which has more info. Perhaps cities1000.zip could be used as a base for you. Maybe you need to create a database with the countries you want, and then perhaps filter the list from the link above by ISO-code or something.
The readme also mentions some continent code, so maybe that can be of use?
