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. | | | adjustOnMutation | boolean | Determines whether or not the <Menu/> should reposition itself based on changes to trigger or reference element position. | false | | renderMode | 'inline' | 'portal' | 'top-layer' | Options to render the popover element * [deprecated] 'inline' will render the popover element inline in the DOM where it's written * [deprecated] 'portal' will render the popover element in a new div appended to the body. Alternatively, can be portaled into a provided portalContainer * 'top-layer' will render the popover element in the top layer | 'top-layer' | | portalContainer (deprecated) | HTMLElement, null | Sets the container used for the popover's portal. | | | scrollContainer (deprecated) | 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 (deprecated) | string | Passes the given className to the popover's portal container if the default portal container is being used. | | | popoverZIndex (deprecated) | 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
