I’d like to use a PopoverMenu with the „traditional“ submenus (not the default sliding ones). According to the documentation this can be archived using gtk_popover_menu_new_from_model_full with the GTK_POPOVER_MENU_NESTED flag. While this seems to work fine I would prefer to set the menu model property directly in the XML file but I can find to way to set the needed flag there.
So is it possible to use nested submenus directly from XML and if yes how do I do it?
