For tabbed content. This exists in some form already on the design system website. See https://github.com/govau/designsystem/blob/master/src/layout/component/navigation-tabs.js
Thanks for the suggestion @rooby.
For clarity actual tabs don’t exist on the design system documentation site yet. That file isn’t real tabs, its just links which look like tabs. Which is also a tracked issue for the documentation site:
GitHub Issue: Component navigation looks like tabs but does not behave like tabs.
