Hi. I added ability to manage how open link with k2 item - on new page or on the same. It is plugin k2 overview map option And now if map has option "Place clustered placemarks on a spiral" and enabled clusterization, then if option is "Yes" - then on max enabled zoom and still clustered placemarks - it is shown on spiral when click on cluster, click on marker - open popupif option is "Title list" - then you can see list above the map, and when click on it - open details for k2 item
Hi. Finally I did release (now will publish into JED too). Action by click for placemarks - you can open Contact Details, Article Details and Placemark details (my placemark item view). I added plugin for K2 and module. Now you can active K2 overview map plugin and pass to K2 overview map module items from K2 - by post and ajax filters. In this case you configure K2 overview map plugin how get data from K2 items (and filter), and just publish K2 overview map module on place where you want to see map. I'll add some description in my documentation for this K2 integration.
