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.
More layouts with navigation: Layout.
Notes for developers

ul
element, so it only supportsli
andscript-supporting

. - Menu needs to collect its node structure, so its children should be
Menu.*
or encapsulated HOCs.
