Components	Navigation	Menu	https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*KeyQQL5iKkkAAAAAAAAAAAAADrJ8AQ/original

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.

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.

Why Menu do not responsive collapse in Flex layout?

Menu will render fully item in flex layout and then collapse it. You need tell flex not consider Menu width to enable responsive (online demo):

<div style={{ flex }}>
  <div style={{ ... }}>Some Content</div>
  <Menu style={{ minWidth: 0, flex: "auto" }} />
</div>
