#### Anchored to Element
React Menu Surface accepts one child element. Please see the below example if you need to anchor the menu surface to a specific element. In this case, we wrapper
> NOTE: also has an onClose callback method prop, which is called when the menu closes. Use this as an opportunity to update your application's state.
`js
import React from 'react';
import MenuSurface, {Corner} from '@material/react-menu-surface';
import Button from '@material/react-button';
class MyApp extends React.Component {
state = {
open: false,
anchorElement: null,
};
setAnchorElement = (element) => {
if (this.state.anchorElement) {
return;
}
this.setState({anchorElement: element});
}
render() {
return (
ref={this.setAnchorElement}
>
anchorCorner={Corner.BOTTOM_LEFT}
onClose={() => this.setState({open: false})}
anchorElement={this.state.anchorElement}
>
src='http://images.my.photo.url' />
#### Anchored to Coordinates (right-click)You may want to anchor your menu surface to x, y coordinates. One example being a right-click contextmenu. Instead of passing an

import React from 'react';
import MenuSurface from '@material/react-menu-surface';class MyApp extends React.Component {
state = {
open: false,
coordinates: null,
};
componentDidMount() {
this.rightClickCallback_ = (evt) => {
this.setState({
open: true,
coordinates: {x: evt.clientX, y: evt.clientY},
});
evt.preventDefault();
};
window.addEventListener('contextmenu', this.rightClickCallback_);
}
componentWillUnmount() {
window.removeEventListener('contextmenu', this.rightClickCallback_);
}
render() {
return (
Menu Surface
onClose={() => this.setState({open: false, coordinates: null})}
coordinates={this.state.coordinates}
>
src='http://images.my.photo.url' />
);
}
}
`> NOTE: The React menu surface component is always hoisted to the body. This is one place the component differs from MDC Web's version, which gives the option of hoisting/not hoisting. Always hoisting the menu surface to the body allows fixes a few issues, and simplifies the component API.
