Velox Map Locator can filter by Type, Group, Country and City.

Prepare the data first

Filters are only as good as the underlying Location data. Standardize country/city values and maintain Type/Group classification before exposing these controls publicly.

Keep the interface focused

A directory with ten Locations may need no filters at all. A multinational dealer network may benefit from country, city and Type. Add controls based on user tasks, not because the option exists.

Test combinations

Try realistic combinations and verify that markers, cards and result counts remain synchronized. If a combination produces no results, make sure that is because the dataset truly has no match.
