    I created an AppBar with a menu based on the examples given on the material UI site and it works fine with one menu. But when I try adding a second dropdown menu, on clicking either icon, I get the same set of MenuItems showing up as seen in the image.

    Here is the list of menu items that are showing up when either icon is clicked

    import React, { Component } from 'react';

// Material UI Imports
import { withStyles } from 'material-ui/styles';
import AppBar from 'material-ui/AppBar';
import Toolbar from 'material-ui/Toolbar';

const styles = {
  root: {
    width: '100%',
  },

    flex: 1,
  },

    paddingLeft: '10px'
  }
}

class Header extends Component {
  constructor(props) {
    super(props);

    this.state = { anchorEl: null };
  }

  handleMenu = event => {
    console.log(event.currentTarget);
    this.setState({ anchorEl: event.currentTarget });
  }

  handleClose = () => {
    this.setState({ anchorEl: null });
  }

  render() {
    const { classes } = this.props;
    const { anchorEl } = this.state;
    const open = Boolean(anchorEl);

    How do you assign which MenuItems show up according to the icon that is clicked? I assumed it was supposed to show the MenuItems that are directly under the selected anchorEl. Any help would be much appreciated!

    Reset to default 12

    Check this working solution https://codesandbox.io/s/84xl2v8wm2 I whipped up

    What I have done is extract the mon code into a separate ponent lets call it MenuButton and use it at multiple places. So that each menu button has its own scope, own event handlers etc. Currently, the issue is that you are using same event handlers for two different elements and using the same variable to keep track of the state of the menu. Either use two variables like open and open1 or extract the code into a separate ponent like I have done.

    Parent file 

    <MenuButton iconType={AccountCircle} items={['Create','List1', 'List2']}/>
<MenuButton iconType={MenuIcon} items={['Profile','User Management', 'Logout']}/>

    menuButton.js file

    import React from 'react';
import AccountCircle from 'material-ui-icons/AccountCircle';
import Menu, { MenuItem } from 'material-ui/Menu';
import IconButton from 'material-ui/IconButton';
import { withStyles } from 'material-ui/styles';

class MenuButton extends React.Component {
  state = {
    anchorEl: null
  };

  handleChange = (event, checked) => {
    this.setState({ auth: checked });
  };

  handleMenu = event => {
    this.setState({ anchorEl: event.currentTarget });
  };

  handleClose = () => {
    this.setState({ anchorEl: null });
  };

  render() {
    const { classes } = this.props;
    const { auth, anchorEl } = this.state;
    const open = Boolean(anchorEl);
    const Wrapper = this.props.iconType;
    const listItems = this.props.items.map((link) =>
      <MenuItem onClick={this.handleClose} >{link}</MenuItem>
    );

    return (
      <div>
        <IconButton
          aria-owns={open ? 'menu-appbar' : null}
          aria-haspopup="true"
          onClick={this.handleMenu}
          color="contrast"
        >
          {<Wrapper />}
        </IconButton>
        <Menu
          id="menu-appbar"
          anchorEl={anchorEl}
          anchorOrigin={{
            vertical: 'top',
            horizontal: 'right',
          }}
          transformOrigin={{
            vertical: 'top',
            horizontal: 'right',
          }}
          open={open}
          onClose={this.handleClose}
        >
        {listItems}


        </Menu>
      </div>
    );
  }

}

export default MenuButton;
