Helsinki Design System | Header

BetaAccessible

The Header component is located at the top of the page above the main body content. It provides a place for levels of primary navigation and site-wide actions.

A work in progress!

The Header components are a collection of new navigation components the HDS team is currently fine tuning. This means that these components are subject to change. We are open to feedback regarding how they work.

Note about Header login components

The Header.LoginButton, Header.LogoutSubmenuButton and Header.UserMenuButton require a working Login Provider that cannot not be configured here. Working examples can be seen in the Storybook.
