Map Category Filter

Category filters let users narrow map items by CMS option field values. Create an Option field in your Webflow CMS, create a Category Filter in Dynamic Map App, update the code embed, and style the filter elements in Webflow. Currently supports Option Fields only — see the Multi-Reference Fields workaround for other field types. Rename CMS options carefully; doing so requires recreating the filter chip.

Map Text Search

Category filters let users narrow down map items by category tags or checkboxes, such as "Sightseeing Spots" or "Nature Parks." This improves the browsing experience and makes large maps far easier to navigate.

💡 Good to Know: Currently, Dynamic Map's category filter only supports the Option Field in Webflow CMS. Need multi-reference field support? Share your feedback here — or see the Multi-Reference Fields workaround guide.

Navigate to your CMS Collection List.
Create an Option field. Each option represents one filterable category.

Troubleshooting

Option 1: Filter Out of Sync

Edit the filter and click Insert Missing Filter Chips. Re-insert the code embed to ensure the snippet is current.

Option 2: Empty Option Fields

If any CMS items have an empty category option field, the entire filter breaks. Fix this by creating a placeholder option (e.g. "empty") and applying it to all items without a real category — then hide it from the UI.
