Using navigation subgroups in custom navigation
Does anyone know how to use navigation subgroups (https://filamentphp.com/docs/3.x/panels/navigation#grouping-navigation-items-under-other-items) in custom navigation (https://filamentphp.com/docs/3.x/panels/navigation#customizing-navigation-groups) ?
Solution
Sharing the solution in case anyone needs it in the future:
NavigationItem::make()->items([child items])
