Restrict map panning to an area | UNL Map JS Docs

Prevent a map from being panned to a different place by setting maxBounds.

Note

If you want to test this example, edit it in JSFiddle or CodePen and replace the "YOUR-OWN-API-KEY" and "YOUR-OWN-VPM-ID" placeholders with your actual api key and vpm id.
