Hello Steffen,

Our components generally fit the design of the app, and you are free to use them in any way they will fit your needs. Thus, we don't make a "header" component per-se, we let the app define the desired container for that.

What we do is to offer helpers for various tasks, for example:

• you can have a toolbar or menu inside the header of your app
• you can use a drawer to generate a sidebar, or put a menu, treeview, panelbar or something else entirely in a sidebar of your design
• we make a list of the components and the general areas they serve in the docs, in the "component list" section: https://docs.telerik.com/blazor-ui/introduction#list-of-components - you may also want to take a peek at the Layout, not only in Navigation section for this type of tasks
• we offer a few sample apps in our New project wizard

Regards,
Marin Bratanov
