We offer surveys to download, no more than 20 surveys files. A specific subset of these 20 files are distributed in Country folders (200+ folders). Furthermore, within each of these country folders there is a set of sub-folders in which we organize our surveys by topic, let's call them Topic-subfolders. E.g. Italy folder ==> Education sub-folder==>Education A survey + Education B survey (the downloadable files).
Here is the current custom solution we have on a Drupal site: Downloadable questionnaire page. We need to find an out-of-the-box solution to replace it for our new WordPress site. As you can see there is a drop-down to select the country and the list of downloadable surveys change according to the user's selection. This specific selector is not necessary, but we need a way for the user to find their country's list of questionnaires divided by topic.
For the back-end, the main characteristic that we are looking for is a tag system that allows us to distribute the surveys within each Topic-subfolders without having to manually copy files. If I remember correctly, you have a master file system that would serve a similar purpose, but I am not sure if it would work for this specific task.
Thanks in advance for your answer,
