Openhab3 sorting items in groups

I am totally confused…
on my sitemap:

    Frame label="Player" {
        Group item=PLAYGROUP label="Player" icon="receiver"
    }

OK, I know If I define on the UI the items, the problem is, that they can’t be sorted. (I already found in the community here).

BUT:
I defined in an several player.items file, but NONE of the items are sorted! Why that? I already defined it in an File, not in the UI.

How Can I solve the problem ?
Thanks,

From the docs on sitemaps:

Attention: There is no way to override the parameters, change the default element type, change the order, use dynamic tags, or insert other elements (e.g. Chart, Image, Webview, etc) in the subframe generated by the Group element.

I found a solution!! in openhab 3 => configuration => sitemap => sort in groups

  • no sort
  • by label
  • by name
