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

• Menu is rendered as a ul element, so it only supports li and script-supporting elements as children nodes。Your customized node should be wrapped by Menu.Item.
• Menu needs to collect its node structure, so its children should be Menu.* or encapsulated HOCs.
• Must set unique key for SubMenu

FAQ

Why will Menu's children be rendered twice?

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.
