Include Metable trait to all menu related classes

[milewski]

Hi, can we have the Metable trait included in the MenuSection, MenuItem, MenuGroup, and MenuList since they all include the Macroable trait? It doesn't serve much purpose if we can't append extra data before JSON serialization.

For instance, I'm currently working on enhancing the UX of larger menus, in this package: Collapsible Resource Manager. It would be far more convenient if I could implement these improvements using the original classes rather than having to extend and create my own.

Hi,

+1 here !

I'm using @milewski dcasia/collapsible-resource-manager for my Nova's apps. This package improve a lot the navigation, overall if application has many modules.

Mainly I would like to:

• add Icon to MenuGroup,

• have ability to prepend or append html to menu section
  

• be able to link section to default resource including if the section has sub menu (this is not allowed currently)

Thank you
