From a user's request, we have added a new drop-down list within the LonelyDrops database.
In this case, we added the list of towns in Spain, which in turn can be linked (if needed) with the list of Spanish provinces.

In the following link, you may find an example of the new list of towns combined with the list of provinces.

For now, the LonelyDrops API does not allow linking and filtering more than two consecutive lists, which means that the three linked lists of autonomous communities, provinces and towns would not conduct a proper filter on the final list.
