menu constant
String
const menu
A type of widget that offers a list of choices to the user.
A menu is often a list of common actions or functions that the user can invoke. The menu role is appropriate when a list of menu items is presented in a manner similar to a menu on a desktop application.
To be keyboard accessible, authors SHOULD manage focus of descendants for all instances of this role, as described in Managing Focus.
