Creative Ways to Customize Material UI Dropdown Menu in React

Material UI is a popular React component library that implements Google's Material Design principles. Among its many components, the Material UI dropdown menu stands out as a versatile tool for enhancing user experience.

Dropdown menus are essential UI elements that allow users to select one or more options from a list.

In this blog, we will delve into the intricacies of creating and customizing dropdown menus using Material UI.

Getting Started with Material UI Dropdown Menus

Before we can start building our dropdown menu, we need to set up our development environment. This involves creating a new React project and installing Material UI.

1// Install Material UI using npm
2npm install @material-ui/core

​

Once installed, we can start using the various components that Material UI offers, including the menu component.

Basic Concepts of Material UI Dropdown Menus

The menu component in Material UI is a powerful UI element that can be customized to fit a wide range of needs. It's important to understand the basic structure of a dropdown menu, which typically consists of a menu button that users click to reveal the menu items.

Creating a Simple Dropdown Menu

To create a simple dropdown menu, we need to import the necessary components from Material UI and define the menu items.

1import React from "react";
2import Menu from "@material-ui/core/Menu";
3import MenuItem from "@material-ui/core/MenuItem";
4
5function SimpleMenu() {
6  const [anchorEl, setAnchorEl] = React.useState(null);
7
8  const handleClick = (event) => {
9    setAnchorEl(event.currentTarget);
10  };
11
12  const handleClose = () => {
13    setAnchorEl(null);
14  };
15
16  return (
17    <div>
18      <Button
19        aria-controls="simple-menu"
20        aria-haspopup="true"
21        onClick={handleClick}
22      >
23        Open Menu{" "}
24      </Button>{" "}
25      <Menu
26        id="simple-menu"
27        anchorEl={anchorEl}
28        keepMounted
29        open={Boolean(anchorEl)}
30        onClose={handleClose}
31      >
32        {" "}
33        <MenuItem onClick={handleClose}>Profile</MenuItem>{" "}
34        <MenuItem onClick={handleClose}>My account</MenuItem>{" "}
35        <MenuItem onClick={handleClose}>Logout</MenuItem>{" "}
36      </Menu>{" "}
37    </div>
38  );
39}

​

In the above example, we have a basic dropdown menu with three menu items. When the menu button is clicked, the menu displays the options for the user to select. Besides simple dropdown menus, Material UI also supports creating 'context menus', which can be triggered by a right-click action.

Customizing Menu Appearance

Material UI provides a range of customization options for dropdown menus. You can style the menu button and apply custom styles to menu items to match your application's design.

1const useStyles = makeStyles((theme) => ({
2  menuItem: {
3    fontWeight: theme.typography.fontWeightBold,
4    color: theme.palette.primary.main,
5  },
6  menuButton: {
7    color: theme.palette.secondary.main,
8  },
9}));
10
11// Inside your component
12const classes = useStyles();
13<Button className={classes.menuButton} onClick={handleClick}>
14  Open Menu
15</Button>
16<MenuItem className={classes.menuItem} onClick={handleClose}>
17  Profile
18</MenuItem>

​

By using the makeStyles hook, we can create custom styles for our menu items and menu button.

Managing Dropdown Menu State

Managing the state of a dropdown menu is crucial for a seamless user experience. We need to control when the menu opens and closes, keep track of the currently selected menu item, and set a 'default value' to demonstrate an already selected option when the menu is first rendered.

1const [selectedItem, setSelectedItem] = React.useState("default value");
2
3const handleMenuItemClick = (value) => {
4  setSelectedItem(value);
5  handleClose();
6};
7
8// Inside the Menu component
9<MenuItem onClick={() => handleMenuItemClick("profile")}>Profile</MenuItem>;

​

In this snippet, we update the selectedItem state with the value of the currently selected menu item when a menu item is clicked, starting with a 'default value' to indicate a pre-selected option in the dropdown menu.

Advanced Dropdown Menu Features

Material UI's dropdown menus can be enhanced with additional features such as multiple select functionality and the use of icons with menu items.

1import Checkbox from '@material-ui/core/Checkbox';
2
3// Inside the Menu component
4<MenuItem onClick={() => handleMenuItemClick('profile')}>
5  <Checkbox checked={selectedItem.includes('profile')} />
6  Profile
7</MenuItem>

​

This code shows how to implement a multiple select dropdown menu where each menu item has a checkbox to indicate selection.

Select Component and Its Variants

The select component is another way to create dropdown menus in Material UI. It comes with different variants, such as the outlined variant, which provides a clear visual boundary for the select field.

1import Select from '@material-ui/core/Select';
2import InputLabel from '@material-ui/core/InputLabel';
3import FormControl from '@material-ui/core/FormControl';
4
5// Inside your component
6<FormControl variant="outlined">
7  <InputLabel htmlFor="outlined-age-native-simple">Age</InputLabel>
8  <Select
9    native
10    value={age}
11    onChange={handleChange}
12    label="Age"
13    inputProps={{ name: 'age', id: 'outlined-age-native-simple'}}
14    >
15	    <option aria-label="None" value="" />
16	    <option value={10}>Ten</option>
17	    <option value={20}>Twenty</option>
18	    <option value={30}>Thirty</option>
19	 </Select>
20</FormControl>

​

In this code snippet, we have a select component with the outlined variant. The InputLabel is associated with the select field using the label prop, enhancing the accessibility of the form control.

Interactivity and Accessibility

Dropdown menus should be interactive and accessible to all users, including those using keyboard navigation or screen readers.

1<Menu
2  id="simple-menu"
3  anchorEl={anchorEl}
4  keepMounted
5  open={Boolean(anchorEl)}
6  onClose={handleClose}
7  MenuListProps={{
8    'aria-labelledby': 'simple-menu-button',
9    onKeyDown: handleListKeyDown,
10  }}
11>
12  {/* Menu items */}
13</Menu>

​

The MenuListProps attribute allows us to pass down additional props to the list component inside the menu, such as aria-labelledby for screen readers and an onKeyDown handler for keyboard navigation.

Popover and Temporary Surfaces

Material UI menus are built on top of the popover component, which acts as a temporary surface for the dropdown content. This allows the menu to be positioned flexibly in relation to the screen’s edge or other elements. Additionally, props can be passed to the 'root element' of the Popover component to customize its behavior and appearance.

1import Popover from '@material-ui/core/Popover';
2
3// Inside your component
4<Popover id={id} open={open} anchorEl={anchorEl} onClose={handleClose} anchorOrigin={{ vertical: 'bottom', horizontal: 'left', }}
5
6{/* Menu content */}
7
8 </Popover>

​

This example demonstrates how to use the popover component directly to create a custom dropdown menu, with control over its positioning.

Integrating Dropdown Menus with Other Components

Dropdown menus can be integrated with other components, such as text fields or as context menus, to provide additional functionality.

1import TextField from "@material-ui/core/TextField";
2
3  // Inside your component
4  return (
5    <TextField
6      select
7      label="Select"
8      value={value}
9      onChange={handleChange}
10      helperText="Please select your currency"
11    >
12      {currencies.map((option) => (
13        <MenuItem key={option.value} value={option.value}>
14          {option.label}
15        </MenuItem>
16      ))}
17    </TextField>
18  );

​

Here, we have a TextField component with a select option, allowing users to choose from a list of currencies. The helper text provides additional information to the user. Simple dialogs can be used in conjunction with dropdown menus to provide additional information or actions related to a selected item, but they are generally less disruptive than simple menus.

Best Practices for Dropdown Menus

When designing dropdown menus, it's important to follow best practices to ensure they are user-friendly and performant. This includes making sure the menu displays correctly on all devices and avoiding common pitfalls such as menu items that are too long or difficult to click.

Troubleshooting Common Issues

Developers often encounter issues such as dropdown menus overlapping other UI elements or problems with menu item selection. It's important to understand how to troubleshoot these issues effectively.

Material UI Dropdown Menu Props and API

Material UI provides a comprehensive list of props and an API for dropdown menus, allowing developers to customize their behavior and appearance to a great extent.

1<Menu
2  id="customized-menu"
3  anchorEl={anchorEl}
4  keepMounted
5  open={Boolean(anchorEl)}
6  onClose={handleClose}
7  PaperProps={{
8    style: {
9      maxHeight: ITEM_HEIGHT * 4.5,
10      width: '20ch',
11    },
12  }}
13>
14  {/* Menu items */}
15</Menu>

​

In this code snippet, we use the PaperProps to customize the style of the dropdown menu, setting a maximum height and width.

Customization Techniques for Dropdown Menus

Customizing dropdown menus in Material UI can involve overriding default styles, extending menus with custom components, or using theme overrides for a consistent look across your application.

Real-world Examples and Use Cases
