Some time ago, every time we started a new project where country or timezone dropdowns were needed, we had to make the effort to maintain and build (almost from scratch) the dropdowns and usually in a multi-language environment (English, Spanish, French, Italian, Catalan, Basque, ...)
Tired of doing these maintenance tasks and manual db loads we prepared a small website that allows anybody to create dynamic dropdown lists with all this data and completely multi-lingual in such an easy way that there's no need to keep these values (country list, timezone list,...) on any additional database. In a matter of seconds, dropdowns will be ready containing, for example, the country list sorted by continents or timezone list sorted by countries.
Send us any suggestions or proposals for new lists and help us to continue improving the service. Thanks!
