Greetings,
there is a situation issue, ... or bug ... or just a need to improuve somehow ....
Well, when more then 1 groups, events or pages are the identical location ( I mean one or more events, pages or posts, groups in the same cluster of items ) , it loads on map as a cluster of items but not open the items on cluster click. I suggest as a posible sollution: even the items markers have the same identical location to expand near eachother the items on cluster click, to be able choose one of them to pop-up .... the list of them into a sigle pop-up will make the pop-up to big.
Hope that's a good idea ....
regards,
B.
