OpenLayers Popup

Basic popup overlay for an 'ol' map. By default the map is centred so that the popup is entirely visible.

Compatible with OpenLayers version 5, 6, 7, 8 and 9 (see note in Install - Parcel, Webpack etc. regarding installing the appropriate version of ol-popup for OpenLayers).

  • Handle DOM events triggered by interacting with elements within the popup content
• Scroll
