UnderlineNav v2

Use an underlined nav to allow tab like navigation with overflow behaviour in your UI.
  • Draft
  • Review pending by accessibility team
import {UnderlineNav} from '@primer/react/drafts'

Examples

Simple

With Icons

Overflow Behaviour

When overflow occurs, the component first hides icons if present to optimize for space and show as many items as possible. (Only for fine pointer devices)

Items Without Icons

Display More Menu

If there is still overflow, the component will behave depending on the pointer.
