Hello. I have a question on dashboard filters. Is it possible to have the filters cascade and be applied to other filters and their values? To exemplify - on my dashboard, I have country and city - so if I select "Germany", I want the listed values for the cities to be filtered as well so I only can choose cities in Germany on the city-filter 🙂

Yes it is possible. Check dependent attribute filters https://help.gooddata.com/doc/enterprise/en/dashboards-and-insights/dashboards/filters-in-dashboards#FiltersinDashboards-Dependentattributefilters
