用法
import {
NavigationMenu,
NavigationMenuContent,
NavigationMenuIndicator,
NavigationMenuItem,
NavigationMenuLink,
NavigationMenuList,
NavigationMenuTrigger,
NavigationMenuViewport,
} from "@/components/ui/navigation-menu"<NavigationMenu>
<NavigationMenuList>
<NavigationMenuItem>
<NavigationMenuTrigger>Item One</NavigationMenuTrigger>
<NavigationMenuContent>
<NavigationMenuLink>Link</NavigationMenuLink>
</NavigationMenuContent>
</NavigationMenuItem>
</NavigationMenuList>
</NavigationMenu>链接
您可以使用 asChild 属性，使另一个组件看起来像导航菜单触发器。以下是一个看起来像导航菜单触发器的链接示例。
import { Link } from "next/link"
export function NavigationMenuDemo() {
return (
<NavigationMenuItem>
<NavigationMenuLink asChild>
<Link href="/docs">Documentation</Link>
</NavigationMenuLink>
</NavigationMenuItem>
)
}
