Material UI is a Material Design library made for React.

It’s a set of React components that have Material Design styles.

In this article, we’ll look at how to add links and menus to Material UI.

Simple Links

We can add links with the Link component.

For instance, we can write:

import React from "react";
import Link from "@material-ui/core/Link";

export default function App() {
  const preventDefault = event => event.preventDefault();
  return (
    <div>
      <Link href="#" onClick={preventDefault}>
        Link
      </Link>
    </div>
  );
}

We add a link with the href to go the URL we want when we click it.

onClick lets us pass in a click handler to change the behavior of the link.

We can also change the color to change the color of the link.

For example, we can write:

import React from "react";
import Link from "@material-ui/core/Link";

export default function App() {
  const preventDefault = event => event.preventDefault();
  return (
    <div>
      <Link href="#" onClick={preventDefault} color="primary">
        Link
      </Link>
    </div>
  );
}

We set the color to primary to make it purple.

Also, we can pass a value to the variant prop to change the styles:

import React from "react";
import Link from "@material-ui/core/Link";
import Typography from "@material-ui/core/Typography";

export default function App() {
  const preventDefault = event => event.preventDefault();
  return (
    <div>
      <Typography>
        <Link href="#" onClick={preventDefault} variant="inherit">
          Link
        </Link>
      </Typography>
    </div>
  );
}

Menus

We can add a menu with the Menu component.

Inside it, we can add items with the MenuItem components.

For example, we can write:

import React from "react";
import Button from "@material-ui/core/Button";
import Menu from "@material-ui/core/Menu";
import MenuItem from "@material-ui/core/MenuItem";
export default function App() {
  const [anchorEl, setAnchorEl] = React.useState(null);
  const handleClick = event => {
    setAnchorEl(event.currentTarget);
  };
  const handleClose = () => {
    setAnchorEl(null);
  };
  return (
    <div>
      <Button onClick={handleClick}>Open</Button>
      <Menu
        anchorEl={anchorEl}
        keepMounted
        open={Boolean(anchorEl)}
        onClose={handleClose}
      >
        <MenuItem onClick={handleClose}>home</MenuItem>
        <MenuItem onClick={handleClose}>profile</MenuItem>
        <MenuItem onClick={handleClose}>logout</MenuItem>
      </Menu>
    </div>
  );
}

to add a menu.

We have a Button that has the onClick prop set to the handleClickfunction.

It sets the anchor element to element so that we can open the menu.

We set the open prop of the menu to the anchor element.

The anchor element would be the button as indicated in the handleClickfunction.

This way, we can determine if the button is clicked and we can open the menu if it’s set.

To close the menu, we set the anchorEl to null so that open will have false passed in.
