This tutorial will guide you through creating a responsive dropdown sidebar menu using HTML, CSS, and JavaScript. This is a great way to enhance the user experience on your website, especially on smaller screens. The menu will adapt seamlessly to various screen sizes, ensuring easy navigation for all users.
Step 1: Include Header Assets
Add the necessary CDN links for styling and fonts within the <head> tag of your HTML document.
<link rel='stylesheet' href='https://unpkg.com/boxicons@2.0.7/css/boxicons.min.css'>
Step 2: Create the HTML Structure
Build the basic structure of your navigation bar, including the logo, navigation links, and search functionality.
<nav>
<div class="navbar">
<i class='bx bx-menu'></i>
<div class="logo"><a href="#">Logo</a></div>
<div class="nav-links">
<div class="sidebar-logo">
<span class="logo-name">Logo</span>
<i class='bx bx-x' ></i>
</div>
<ul class="links">
<li><a href="#">HOME</a></li>
<li>
<a href="#">HTML & CSS</a>
<i class='bx bxs-chevron-down htmlcss-arrow arrow '></i>
<ul class="htmlCss-sub-menu sub-menu">
<li><a href="#">Web Design</a></li>
<li><a href="#">Login Forms</a></li>
<li><a href="#">Card Design</a></li>
<li class="more">
<span><a href="#">More</a>
<i class='bx bxs-chevron-right arrow more-arrow'></i>
</span>
<ul class="more-sub-menu sub-menu">
<li><a href="#">Neumorphism</a></li>
<li><a href="#">Pre-loader</a></li>
<li><a href="#">Glassmorphism</a></li>
</ul>
</li>
</ul>
</li>
<li>
<a href="#">JAVASCRIPT</a>
<i class='bx bxs-chevron-down js-arrow arrow '></i>
<ul class="js-sub-menu sub-menu">
<li><a href="#">Dynamic Clock</a></li>
<li><a href="#">Form Validation</a></li>
<li><a href="#">Card Slider</a></li>
<li><a href="#">Complete Website</a></li>
</ul>
</li>
<li><a href="#">ABOUT US</a></li>
<li><a href="#">CONTACT US</a></li>
</ul>
</div>
<div class="search-box">
<i class='bx bx-search'></i>
<div class="input-box">
<input type="text" placeholder="Search...">
</div>
</div>
</div>
</nav>
Step 3: Style with CSS
Apply CSS styles to create the visual appearance of your menu, including responsiveness for different screen sizes.

Step 4: Add JavaScript Functionality
Implement JavaScript to handle the interactive elements of the menu, such as opening and closing the sidebar and submenus, and the search functionality.
// search-box open close js code
let navbar = document.querySelector(".navbar");
let searchBox = document.querySelector(".search-box .bx-search");
// let searchBoxCancel = document.querySelector(".search-box .bx-x");
searchBox.addEventListener("click", ()=>{
navbar.classList.toggle("showInput");
if(navbar.classList.contains("showInput")){
searchBox.classList.replace("bx-search" ,"bx-x");
}else {
searchBox.classList.replace("bx-x" ,"bx-search");
}
});
// sidebar open close js code
let navLinks = document.querySelector(".nav-links");
let menuOpenBtn = document.querySelector(".navbar .bx-menu");
let menuCloseBtn = document.querySelector(".nav-links .bx-x");
menuOpenBtn.onclick = function() {
navLinks.style.left = "0";
}
menuCloseBtn.onclick = function() {
navLinks.style.left = "-100%";
}
// sidebar submenu open close js code
let htmlcssArrow = document.querySelector(".htmlcss-arrow");
htmlcssArrow.onclick = function() {
navLinks.classList.toggle("show1");
}
let moreArrow = document.querySelector(".more-arrow");
moreArrow.onclick = function() {
navLinks.classList.toggle("show2");
}
let jsArrow = document.querySelector(".js-arrow");
jsArrow.onclick = function() {
navLinks.classList.toggle("show3");
}
Congratulations! You have successfully created a responsive dropdown sidebar menu using HTML, CSS, and JavaScript. Enjoy!
