Hi. Sorry, I was busy and there was no automatic mails from forum.
The main thing of calling by category or group - it was get placemarks by this parameter.
And the other map objects was loaded just connected to map.
* you have placemarks 1,2,3,4 which is Category1
* you have placemarks 5,6,7,8 which is Category2
* you have path 1, connected to map1
If you call placemarks by Category1 and show on map2 - you'll see only placemarks.
If you call placemarks by Category 1 and show it on map1 - you'll see path too.
If you call by Category 2 and show on map1 - the same - you'll see path
Thank you for the answer!
What I would like to do is to show all paths belonging to Category 1 in Map 1. Other paths are also connected to Map 1, but I want to show only paths från Category 1. (Showing placemarks not necessary). Like a filter. So it would be the same functionality as calling placemarks I guess, but paths instead. If it´s possibly it would be really good, it would make Zh Google maps even more flexible.
