Option to render menu with display:none when closed?

[angusmoncrieff]

Hello and thank you for this library!

I have built a menu with submenus using react-menu-list which contains links to other places on my web app. I would like these links to be visible to google crawlers, but at present the menu doesn't exist in the DOM until it's clicked.

Could there be an option so that menu and submenus are always rendered to the DOM, albeit with display:none when the menu is closed? (I.e. same as how reactstrap renders dropdowns.)

(FYI my submenus are only one level: i.e. the parent menu has multiple submenus, but no submenu has submenus.)

Perhaps I could have a go at this myself, but I'd greatly appreciate any insight you might have.
