Prioritize and Sort Navigation Menu Items Groups

Menu Priority

You can use :first, :last or any integer number.

Menu Item Priority

This will contribute to sorting of the group as well.

menu do
  item :my_menu_item, icon: "fa fa-star", group: :my_group_name, priority: :first
end

Menu Group Priority

You can use the block version of group to give priority to a group as well.

menu do
  group :group_name, priority: 100 do
    item :resource, icon: "fa fa-star", priority: 1
  end
end
