Placemark groups and Items switching by click

Hello,

I have made a simple map with about 25 placemark groups at bit.ly/19lczt4 .
Is there a possibility (code change or already featured possibility) to switch kml layers by groups menu items?
e.g. You press number one item, it shows on the map. You press number two item, numer one is switching off, and map shows number two item etc)
If there is, please what is the way to achieve it.
Thx in advance and regards.

Hi.

But you can do this.
In map details, open "Placemark Groups" slider
As you know, you use placemark management ("Manage Placemarks" is set to Yes)
Now if you enable "Manage Paths" (set it to KML layers), you can manage your KML files.
Open your path with KML layer, and set it group assignment (as you did for placemarks)

And after that your KML layers will show/hide

You can see it in my demo

joomla.zhuk.cc/index.php/zhgooglemap-dem...re-managebygroup-kml

Hi,
I have already set the feature from your demo before I have made the first post.
I have not explained enough the problem I would like to solve, so I will try to clarify it by your demo at joomla.zhuk.cc/index.php/zhgooglemap-dem...re-managebygroup-kml :

1. When you enter the demo page, Spain kml is shown
2. when you click any item on right (e.g. Germany), the KML layer shows on map
3. now, both layers clicked are shown on the map

I would like to achieve toggling - when you click the second item ( e.g. Germany mentioned in ad.2), the first item automaticaly hide (Spain hides, Germany is switched on). And so on - if you click Switzerland, Germany kml hides and only Switz kml is shown etc.

I hope I clarify my question now, sorry I haven't been precise enough in my first post.
Can you help me to solve this question?
Thx in advance and rgds

Aha. Now I understand you.

No. Today there is no feature to toggle. May be in future I'll do this and the other

Now I'm totally change my code (I expect to do release in 1-2 weeks), and after that I can have (I think), more flexible code to do different funny features.
The main thing now - ajax loading placemarks (not only it's content), in this case a lot of placemarks will be loaded dynamically and map will show immediately.
