Placemark group is not displayed

I just did a comparison of my code to an example with group list which I found at the net. I could not find a single hint of the word group. In the example code there are instances of "groupListBodyTopContent", "zhgm-markergroup-a-markergroup" and so on.

Now for sure it is clear that I don't get a group list when it doesn't appears at the code.
But still don't know which parameter has to be set?

Active in Placemark Group : Yes , Is set in every group.

The other settings are seen in my attachments.

Any help is much appreciated.

In this case can you save all page source with map, not cut only my code. And attach it me

Hi Dima,

please find attached the Code of the whole page.

In your case you show map by plugin, ie in an article.

Placemark management by group list doesn't supported in plugin. I wrote it in docs.
If you want to show/hide placemarks (and or KML files) - you should use component call (menu map item), or module

I used the module call methode and put it by {loadposition ...} command in my article. Now it show's up with placemark group list. Many thanks for your help.
