INTER Polska
Insurance company · facility finder and page-builder blocks
INTER Polska is a Polish insurance company. On a contract with the Webcost agency I added new blocks to its custom page builder and built the finder that shows the nearest medical facilities and branches on a map.

The task
Clients of the insurer need to find the nearest partner clinic or branch quickly, often from a phone. The map and the list of addresses had to work together, so a click in one place shows the same location in the other.
- Find the nearest facility by city or by location
- A map and a list that stay in sync
- New blocks the marketing team can place on any page
What I built
Facility finder
- A custom template for WP Store Locator with quick buttons for the main cities, a search field and a “find my location” button.
- A Google Map with marker clustering. Locations load over AJAX, so the page stays light.
- When a marker is clicked, the matching address in the side list is found, scrolled into view and highlighted.
- The same finder works for medical facilities and for branches.
Page builder
- New blocks and forms for the theme’s own page builder.
- Every block loads its own CSS, split into the part above the fold and the part below it.
Outcome
- finders, facilities and branches
- 2
- click links the map and the list
