Introduction

A responsive navigation menu adapts to different screen sizes, ensuring a seamless user experience across devices. In this tutorial, we'll create a navigation menu that collapses into a hamburger menu on smaller screens and expands on larger ones.

Setting Up the Project

First, let's set up a new React project using Create React App:

npx create-react-app responsive-nav-menu
cd responsive-nav-menu
npm start

Creating the Basic Structure

Let's start by creating a basic navigation component. Create a new file called NavMenu.js in the src directory:

import React, { useState } from 'react';

const NavMenu = () => {
  const [isOpen, setIsOpen] = useState(false);

  const toggleMenu = () => {
    setIsOpen(!isOpen);
  };

  return (
    <nav className="nav-menu">
      <div className="nav-logo">Logo</div>
      <ul className={`nav-links ${isOpen ? 'active' : ''}`}>
        <li><a href="#home">Home</a></li>
        <li><a href="#about">About</a></li>
        <li><a href="#services">Services</a></li>
        <li><a href="#contact">Contact</a></li>
      </ul>
      <div className="nav-toggle" onClick={toggleMenu}>
        <span></span>
        <span></span>
        <span></span>
      </div>
    </nav>
  );
};

export default NavMenu;

This component creates a basic structure for our navigation menu, including a logo, navigation links, and a toggle button for mobile views.

Styling the Navigation Menu

Now, let's add some basic styles to our navigation menu. Create a new file called NavMenu.css in the src directory:

.nav-menu {
  display: flex;
  justify-content: space-between;
  align-items: center;
  padding: 1rem 2rem;
  background-color: #333;
  color: #fff;
}

.nav-logo {
  font-size: 1.5rem;
  font-weight: bold;
}

.nav-links {
  display: flex;
  list-style: none;
}

.nav-links li {
  margin-left: 1rem;
}

.nav-links a {
  color: #fff;
  text-decoration: none;
}

.nav-toggle {
  display: none;
  flex-direction: column;
  cursor: pointer;
}

.nav-toggle span {
  width: 25px;
  height: 3px;
  background-color: #fff;
  margin-bottom: 5px;
}

@media (max-width: 768px) {
  .nav-links {
    display: none;
  }

  .nav-links.active {
    display: flex;
    flex-direction: column;
    position: absolute;
    top: 60px;
    left: 0;
    right: 0;
    background-color: #333;
  }

  .nav-links li {
    margin: 1rem 0;
  }

  .nav-toggle {
    display: flex;
  }
}

Don't forget to import the CSS file in your NavMenu.js:

import './NavMenu.css';

Adding Responsiveness

Our CSS already includes some responsive styles, but let's enhance it further by adding smooth transitions:

.nav-links {
  display: flex;
  list-style: none;
  transition: all 0.3s ease-in-out;
}

@media (max-width: 768px) {
  .nav-links {
    transform: translateY(-100%);
    opacity: 0;
    pointer-events: none;
  }

  .nav-links.active {
    transform: translateY(0);
    opacity: 1;
    pointer-events: auto;
  }
}

Implementing a Hamburger Menu

Let's create a separate component for our hamburger menu icon. Create a new file called HamburgerIcon.js:

import React from 'react';

const HamburgerIcon = ({ isOpen, toggleMenu }) => {
  return (
    <div className={`hamburger ${isOpen ? 'open' : ''}`} onClick={toggleMenu}>
      <span></span>
      <span></span>
      <span></span>
    </div>
  );
};

export default HamburgerIcon;

Now, update the NavMenu.js to use this new component:

import React, { useState } from 'react';
import HamburgerIcon from './HamburgerIcon';
import './NavMenu.css';

const NavMenu = () => {
  const [isOpen, setIsOpen] = useState(false);

  const toggleMenu = () => {
    setIsOpen(!isOpen);
  };

  return (
    <nav className="nav-menu">
      <div className="nav-logo">Logo</div>
      <ul className={`nav-links ${isOpen ? 'active' : ''}`}>
        <li><a href="#home">Home</a></li>
        <li><a href="#about">About</a></li>
        <li><a href="#services">Services</a></li>
        <li><a href="#contact">Contact</a></li>
      </ul>
      <HamburgerIcon isOpen={isOpen} toggleMenu={toggleMenu} />
    </nav>
  );
};

export default NavMenu;

Add some styles for the hamburger icon in NavMenu.css:

.hamburger {
  display: none;
  flex-direction: column;
  cursor: pointer;
}

.hamburger span {
  width: 25px;
  height: 3px;
  background-color: #fff;
  margin-bottom: 5px;
  transition: all 0.3s ease-in-out;
}

.hamburger.open span:nth-child(1) {
  transform: rotate(45deg) translate(5px, 5px);
}

.hamburger.open span:nth-child(2) {
  opacity: 0;
}

.hamburger.open span:nth-child(3) {
  transform: rotate(-45deg) translate(7px, -6px);
}

@media (max-width: 768px) {
  .hamburger {
    display: flex;
  }
}

Enhancing Accessibility

To improve accessibility, let's add ARIA attributes and keyboard navigation:

import React, { useState, useRef, useEffect } from 'react';
import HamburgerIcon from './HamburgerIcon';
import './NavMenu.css';

const NavMenu = () => {
  const [isOpen, setIsOpen] = useState(false);
  const navRef = useRef(null);

  const toggleMenu = () => {
    setIsOpen(!isOpen);
  };

  useEffect(() => {
    const handleOutsideClick = (event) => {
      if (navRef.current && !navRef.current.contains(event.target)) {
        setIsOpen(false);
      }
    };

    document.addEventListener('mousedown', handleOutsideClick);
    return () => {
      document.removeEventListener('mousedown', handleOutsideClick);
    };
  }, []);

  const handleKeyPress = (event) => {
    if (event.key === 'Enter' || event.key === ' ') {
      toggleMenu();
    }
  };

  return (
    <nav className="nav-menu" ref={navRef}>
      <div className="nav-logo">Logo</div>
      <ul className={`nav-links ${isOpen ? 'active' : ''}`} role="menu">
        <li role="none"><a href="#home" role="menuitem">Home</a></li>
        <li role="none"><a href="#about" role="menuitem">About</a></li>
        <li role="none"><a href="#services" role="menuitem">Services</a></li>
        <li role="none"><a href="#contact" role="menuitem">Contact</a></li>
      </ul>
      <HamburgerIcon 
        isOpen={isOpen} 
        toggleMenu={toggleMenu} 
        onKeyPress={handleKeyPress}
        aria-expanded={isOpen}
        aria-label="Toggle menu"
      />
    </nav>
  );
};

export default NavMenu;

Update the HamburgerIcon.js component:

import React from 'react';

const HamburgerIcon = ({ isOpen, toggleMenu, onKeyPress, ...props }) => {
  return (
    <div 
      className={`hamburger ${isOpen ? 'open' : ''}`} 
      onClick={toggleMenu}
      onKeyPress={onKeyPress}
      tabIndex="0"
      role="button"
      {...props}
    >
      <span></span>
      <span></span>
      <span></span>
    </div>
  );
};

export default HamburgerIcon;

Performance Optimization

To optimize performance, we can use React.memo to prevent unnecessary re-renders:

import React, { memo } from 'react';

const HamburgerIcon = memo(({ isOpen, toggleMenu, onKeyPress, ...props }) => {
  return (
    <div 
      className={`hamburger ${isOpen ? 'open' : ''}`} 
      onClick={toggleMenu}
      onKeyPress={onKeyPress}
      tabIndex="0"
      role="button"
      {...props}
    >
      <span></span>
      <span></span>
      <span></span>
    </div>
  );
});

export default HamburgerIcon;

Advanced Features

Let's add a dropdown menu to our navigation:

import React, { useState, useRef, useEffect } from 'react';
import HamburgerIcon from './HamburgerIcon';
import './NavMenu.css';

const NavMenu = () => {
  const [isOpen, setIsOpen] = useState(false);
  const [dropdownOpen, setDropdownOpen] = useState(false);
  const navRef = useRef(null);

  const toggleMenu = () => {
    setIsOpen(!isOpen);
  };

  const toggleDropdown = () => {
    setDropdownOpen(!dropdownOpen);
  };

  useEffect(() => {
    const handleOutsideClick = (event) => {
      if (navRef.current && !navRef.current.contains(event.target)) {
        setIsOpen(false);
        setDropdownOpen(false);
      }
    };

    document.addEventListener('mousedown', handleOutsideClick);
    return () => {
      document.removeEventListener('mousedown', handleOutsideClick);
    };
  }, []);

  const handleKeyPress = (event) => {
    if (event.key === 'Enter' || event.key === ' ') {
      toggleMenu();
    }
  };

  return (
    <nav className="nav-menu" ref={navRef}>
      <div className="nav-logo">Logo</div>
      <ul className={`nav-links ${isOpen ? 'active' : ''}`} role="menu">
        <li role="none"><a href="#home" role="menuitem">Home</a></li>
        <li role="none"><a href="#about" role="menuitem">About</a></li>
        <li role="none" className="dropdown">
          <a href="#services" role="menuitem" onClick={toggleDropdown}>Services</a>
          {dropdownOpen && (
            <ul className="dropdown-menu" role="menu">
              <li role="none"><a href="#service1" role="menuitem">Service 1</a></li>
              <li role="none"><a href="#service2" role="menuitem">Service 2</a></li>
              <li role="none"><a href="#service3" role="menuitem">Service 3</a></li>
            </ul>
          )}
        </li>
        <li role="none"><a href="#contact" role="menuitem">Contact</a></li>
      </ul>
      <HamburgerIcon 
        isOpen={isOpen} 
        toggleMenu={toggleMenu} 
        onKeyPress={handleKeyPress}
        aria-expanded={isOpen}
        aria-label="Toggle menu"
      />
    </nav>
  );
};

export default NavMenu;

Add styles for the dropdown menu in NavMenu.css:

.dropdown {
  position: relative;
}

.dropdown-menu {
  display: none;
  position: absolute;
  top: 100%;
  left: 0;
  background-color: #444;
  padding: 0.5rem 0;
  list-style: none;
  min-width: 150px;
}

.dropdown-menu li {
  padding: 0.5rem 1rem;
}

.dropdown-menu a {
  color: #fff;
  text-decoration: none;
}

.dropdown:hover .dropdown-menu,
.dropdown-menu:hover {
  display: block;
}

@media (max-width: 768px) {
  .dropdown-menu {
    position: static;
    background-color: #555;
  }
}
