Standalone navigation
This page sets layout.showHeader = false and layout.showNav = true — no layout.header on the page at all, just layout.nav.
What's configured here (see config/page_level/showcase-navigation.config.php):
layout.showHeader = false,layout.showNav = true— the nav above the page title islayout.navrendering with no header present at all.- Resize the window narrow enough and it collapses to the same hamburger/drawer behaviour it would use inside a header — nav owns that presentation itself.
Same component, different config, dropped in here
A second layout.nav call, mid-page, with its own mobileNavMode: 'dropdown' and navSide: 'left' — independent of the one above.
