How to reorder the navigation

Hi i have a problem where i can not move mine resource navigation link under the Group, i used

public static function getNavigationSort() :?int
    {
        return 9;
    }

public static function getNavigationSort() :?int
    {
        return 9;
    }

` The last link in the group has this value

public static function getNavigationSort() :?int
    {
        return 8;
    }

public static function getNavigationSort() :?int
    {
        return 8;
    }

Solution

Navigation items are sorted by group first and by item second. Means you cannot put an item without a group below a group
