Multiselect lets users select multiple categories at the same time. This can create powerful filters, but it works best when your audience benefits from combining selections.
If you’re looking for a simpler filtering experience for most users, start with: Categories & Filters: How Map Filtering Works?
When Should I Use Multiselect?
- You want users to combine filters (for example: “Under $500k” + “2 Bedrooms” + “For Sale”)
- Your map is a directory and users need advanced search
- You expect users to compare results across categories
If your map is a building or floor map, Single Selection with Parent Category View is often a better experience.

Note: Multiselect can also be used on maps with a single category level. In most cases, the added flexibility is outweighed by the extra complexity for users—so we recommend enabling it only when you have a clear use case.
Multiselect Relationship Settings
In Multiselect mode, you can control how multiple selections work together:
- Relationship between parent categories (when users select more than one parent)
- Relationship between parent and subcategories (how a parent and its subcategories combine)
- Relationship between subcategories (when users select more than one subcategory)
To understand what Combine and Intersect mean in each case, see: Category Filter Settings
Recommended Settings by Use Case
Real Estate Listings
Common pattern: locations are assigned to subcategories (values) such as price range, number of bedrooms, property type, and more.
Parent categories often describe the filter group (for example: “Pricing” or “Bedrooms”).
- Relationship between parent categories: Intersect
- Relationship between parent and subcategories: Combine
- Relationship between subcategories: Combine
Project Portfolios
Project portfolio maps typically benefit from flexible browsing and showing broader results.
- Relationship between parent categories: Combine
- Relationship between parent and subcategories: Combine
- Relationship between subcategories: Combine
City Guides
City guides usually prioritize discovery, so settings that show broader results tend to work best.
- Relationship between parent categories: Combine
- Relationship between parent and subcategories: Combine
- Relationship between subcategories: Combine
Tip: “Others” When Some Locations Are Only in Parent Categories
If some locations are assigned to a parent category but not to any subcategory, Mapme may show an “Others” group in certain filter combinations.
Others includes locations that belong to the parent category but are not assigned to any subcategory.
