Usage with NextJS Link components

We recommend using Menu with NextJS's links components in the following pattern:

import NextLink from 'next/link';

function CustomLink({ href, children, ...props }) {
  return (
    <NextLink href={href}>
      <a {...props}>
        {children}
      </a>
    </NextLink>
  );
}

<Menu trigger={<button onClick={handleClick}>trigger</button>} open={open}>
  <MenuItem as={CustomLink} href="/test">
    Test
  </MenuItem>
  <SubMenu
    title="Submenu"
    href="http://mongodb.design"
  >
    <MenuItem>SubMenu Item 1</MenuItem>
    <MenuItem as={CustomLink} href="/test-2">
      SubMenu Item 2
    </MenuItem>
  </SubMenu>
</Menu>

This pattern is recommended given the SubMenu component expects to pass styling through the className prop, which would not apply correctly if it was passed to NextLink.

In other words, defining a MenuItem as:

<MenuItem as={CustomLink} href="/test-2">
  SubMenu Item 2
  </MenuItem>

would render, but without the correct styles.

Properties

Prop	Type	Description	Default
`open`	`boolean`	Determines whether or not the `<Menu />` will appear as open or closed	`false`
`setOpen`	`function`	When controlling the component, use `setOpen` to keep track of the `<Menu />` component's state so that clicks on the document's backdrop as well as a user pressing the Escape Key will close the Menu and update the consuming application's local state accordingly.
`initialOpen`	`boolean`	Passes an initial value for "open" to an uncontrolled menu	`false`
`shouldClose`	`function`	Determines if the `Menu` should close when the backdrop or Escape keys are clicked. Defaults to true.	`() => true`
`align`	`'top'`, `'bottom'`, `'left'`, `'right'`	Determines the alignment of the `<Menu />` component relative to a reference element, or the element's nearest parent	`'bottom'`
`justify`	`'start'`, `'middle'`, `'end'`	Determines the justification of the `Menu` component (based on the alignment) relative to a reference element or the element's nearest parent	`'end'`
`refEl`	`HTMLElement`	Pass a reference to an element that the `Menu` component should be positioned against
`trigger`	`function`, `React.ReactNode`	A `ReactNode` against which the Menu will be positioned. The trigger prop can also support being passed a function. To work as expected, the function must accept an argument of `children`, which should be rendered inside of the function passed to trigger.
`usePortal`	`boolean`	Will position Menu's children relative to its parent without using a Portal if `usePortal` is set to false. NOTE: The parent element should be CSS position relative, fixed, or absolute if using this option.	`true`
`adjustOnMutation`	`boolean`	Determines whether or not the `<Menu/>` should reposition itself based on changes to `trigger` or reference element position.	`false`
`usePortal`	`boolean`	Determines if the Menu will be rendered within a portal.	`true`
`portalContainer`	`HTMLElement`, `null`	Sets the container used for the popover's portal.
`scrollContainer`	`HTMLElement`, `null`	If the popover portal has a scrollable ancestor other than the window, this prop allows passing a reference to that lement to allow the portal to position properly.
`portalClassName`	`string`	Passes the given className to the popover's portal container if the default portal container is being used.
`popoverZIndex`	`number`	Sets the z-index CSS property for the popover.
`darkMode`	`boolean`	Determines whether or not the component will be rendered in dark theme.

Any other properties will be spread on the Menu ul container

MenuItem

Properties

Prop	Type	Description	Default
`href`	`string`	If supplied, will render the `<MenuItem />` inside of an `<a>` tag, rather than a `<button>` tag
`children`	`node`	Content to appear inside of `<MenuItem />` component
`className`	`string`	Classname applied to `li` element
`onClick`	`function`	Function that will be called when a `<MenuItem />` is clicked
`active`	`boolean`	Determines if the `<MenuItem />` is `active`	`false`
`disabled`	`boolean`	Determines if the `<MenuItem />` is `disabled`	`false`
`description`	`node`	Content to appear below main text of the `<MenuItem />`
`as`	`React.ElementType`	Determines what the `<MenuItem />` will be rendered as
`size`	`default`, `large`	Size of the `<MenuItem />` component	`'default'`
`glyph`	`React.ReactElement`	Slot to pass in an Icon rendered to the left of `<MenuItem />` text.
`variant`	`'default', 'destructive'`	Determines variant of `<MenuItem />` component	`'default'`
...	native attributes of component passed to `as` prop	Any other props will be spread on the root element

SubMenu

Properties

Prop	Type	Description	Default
`open`	`boolean`	Determines if `<SubMenu />` item appears open	`false`
`setOpen`	`function`	Function to set the value of `open` in `<SubMenu />`

`href`	`string`	If supplied, will render the `<SubMenu />` inside of an `<a>` tag, rather than a `<button>` tag
`spacing`	`number`	Distance between the content rendered inside of the Menu and the trigger	`15`
...	native `anchor` or `button` attributes	Any other props will be spread on the root element
