I've also added a setter to DataTrigger, to make separators unselectable:

Erratum:
In post #3, should read
“…general-purpose ObservableCollection instead of ObservableCollection…”

Thomas, you’re right.

But IMHO I prefer not to have any UI-related stuff in my ViewModel classes

If you don’t mind using the more general-purpose ObservableCollection instead of ObservableCollection, then you could simply add a Separator object in the binding source:

DataContext = new ObservableCollection
{
“Catergory 1″,
new Separator(),
“Catergory 2″,
“Catergory 3″,
};

Bien vu !
On pouvait aussi faire ça avec la propriété ItemTemplateSelector… mais c’est vrai que c’est classe de tout faire en XAML
