Base UITransitions
Menu
Base UI folds dropdown and menubar surfaces into one Menu component.
Every value the manifest allows on this host, single presets and the pairs that compose. The first is what this component ships with. Both stages are the same component, so anything that changes between them is the attribute.

Where the attribute goes
The parts this demo composes, and the value each one carries. Everything inside an animated part is that part's content, so the tree stops there.

Source
"use client"
import { Menu } from "@base-ui/react/menu"
import type { DemoProps } from "@/components/demos/props"
export function BaseUiMenu({ motion }: DemoProps) {
return (
<Menu.Root>
<Menu.Trigger className="btn">Open menu</Menu.Trigger>
<Menu.Portal>
<Menu.Positioner sideOffset={10} collisionPadding={16}>
<Menu.Popup className="menu" data-motion={motion}>
<Menu.Item className="menu__item">Rename</Menu.Item>
<Menu.Item className="menu__item">Duplicate</Menu.Item>
<Menu.Item className="menu__item">Archive</Menu.Item>
</Menu.Popup>
</Menu.Positioner>
</Menu.Portal>
</Menu.Root>
)
}motion prop is the only difference between them.
