I\'m using Leaflet JS to build a custom map (with custom tiles), it loops East to West. I\'ve added a couple layers of markers and polygons (to indicate a route in the map)
Use 'worldCopyJump': true
in your map options.
With this option enabled, the map tracks when you pan to another "copy" of the world and seamlessly jumps to the original one so that all overlays like markers and vector layers are still visible.
