Header

Header is a sticky top navigation bar built as a compound component. It is meant for layout composition rather than variant switching, so the public API stays intentionally small: Header, HeaderContent, HeaderLeft, HeaderCenter, and HeaderRight.

Centered content

HeaderCenter is a flex item that fills the available space between the left and right sections. It works well for search bars and centered tools.

Navigation menus

Use the NavigationMenu primitives for dropdown menus and multi-level navigation. NavigationMenu renders the viewport automatically by default, and NavigationMenuIndicator should be placed after NavigationMenuList when you want the active indicator arrow.

Sidebar layouts

When a sidebar already owns branding, use container={false} so the header can span the full width without an extra max-width wrapper.

Full-width and custom backgrounds

Header accepts native className overrides, so you can apply gradients, transparent borders, or other visual treatments without changing the component implementation.
