How do I do custom shapes (Complex Multipoint Geometry) using Geofield and Leaflet?
I think this is already possible when using Geofield with OpenLayers. Although I'm not using complex geometries in my current case, all settings indicate that the module is capable of it. E.g. if you choose in the setting of your Geofield for the storage option for 'single collection' it indicates that the widget will allow complex geometries.
