A versatile menu for navigation.
When To Use
Navigation is an important part of any website, as a good navigation setup allows users to move around the site quickly and efficiently. Ant Design offers two navigation options: top and side. Top navigation provides all the categories and functions of the website. Side navigation provides the multi-level structure of the website.

Notes for developers

ulelement, so it only supportsliandscript-supportingelements as children nodes。Your customized node should be wrapped byMenu.Item. - Menu needs to collect its node structure, so its children should be 
Menu.*or encapsulated HOCs. - Must set unique key for 
SubMenu

Menu collects structure info with twice-render to support HOC usage. Merging into one render may cause the logic to become much more complex. Contributions to help improve the collection logic are welcomed.
