Overview

Port of registry/new-york-v4/ui/navigation-menu.tsx, whose behaviour is Radix's NavigationMenu — 1,403 lines against shadcn's 168, vendored at vendor/radix/ui/navigation-menu.tsx.

data-viewport is always false here, and that is the decision this port turns on. Upstream's default renders every panel into one shared box that animates between their sizes — measured on the live demo, the content's parent is navigation-menu-viewport, which means React has moved it there through a portal. Nothing is portalled in this gem, for the reason in decisions/02-javascript.md, so that mode cannot be reproduced without giving up the rule every other component here was built on.

viewport={false} is not a workaround: it is a configuration shadcn supports and ships classes for, and in it each panel stays inside its own item with its own border, background and shadow. See features/navigation-menu.md.

Constructor Details

#initialize(delay_duration: 200, skip_delay_duration: 300, **attributes) ⇒ Component

Radix's own defaults (navigation-menu.tsx:136-137). skip_delay_duration is the grace period after a panel closes in which the next one opens at once — it is what stops a menu feeling sticky when you sweep across it.
