Responsive multi-level dropdown navigation bar tutorial using HTML, CSS, and JavaScript

In this blog post, we will create a Responsive Multi-level Dropdown Navigation Bar using HTML, CSS, and JavaScript.

When we talk about creating a professional website, one of the first things that comes to mind is the Navigation Bar (Navbar).
It is the gateway for visitors to explore different sections of your website. Without a well-designed navigation bar, users may feel lost, and your website could fail to deliver a smooth browsing experience.

We will not only provide the complete code but also explain each step so that you can easily implement it on your website.

Why Do You Need a Navigation Bar?

A navigation bar is one of the most important parts of web design. Let’s look at why it is essential:

  1. Improves User Experience – It helps visitors quickly find the information they are looking for.
  2. Enhances Website Design – A stylish navbar makes your website look modern and professional.
  3. SEO Friendly – Proper navigation structure helps search engines crawl your site efficiently.
  4. Mobile Friendly Browsing – A responsive navbar ensures mobile users can also navigate easily.
  5. Organizes Content – Multi-level dropdown menus let you organize services, categories, or product lists in a structured way.

Features of Our Multi-level Dropdown Navigation Bar

The navigation bar we are building in this tutorial will have the following features:

  • Fully responsive design that works on all screen sizes.
  • Multi-level dropdown menus for nested categories.
  • A search bar toggle option at the top.
  • Hamburger icon for showing and hiding the menu on smaller screens.
  • Clean, modern, and dark theme design with hover effects.
  • Simple and lightweight – only HTML, CSS, and vanilla JavaScript are used.

HTML Code:

We’ll start with the HTML structure.
This code defines the logo, navigation menu, dropdowns, search bar, and mobile menu button.

  .sub-sub-menu {
    display: none;
  }

  .submenushow,
  .show-sub-sub-menu {
    display: block;
  }

}

JavaScript Code:

Now let’s add JavaScript to handle search toggle, mobile menu toggle, and dropdown expansion.

const seaCont = document.getElementById("top-search");
const serHide = document.getElementById("topsercross-icon");
const serShow = document.getElementById("ser-btn-icon");

serShow.addEventListener("click", () => {
  seaCont.style.padding = "5px 5%";
  seaCont.style.height = "50px";
  seaCont.style.transition = "all 0.5s";
});

serHide.addEventListener("click", () => {
  seaCont.style.height = "0";
  seaCont.style.padding = "0 5%";
});

// =============Navbar Hide and Show==============

const barbtn = document.getElementById("bar-icon");
const dropdown = document.getElementById("menu");

barbtn.addEventListener("click", () => {
  dropdown.classList.toggle("show");
});

// =============submenu====================

const droptog = document.querySelectorAll(".droptoggle");
const submenu = document.getElementsByClassName("submanu");

for (let x = 0; x < droptog.length; x++) {
  droptog[x].addEventListener("click", () => {
    submenu[x].classList.toggle("submenushow");
  });
}

// ============sub=sub=dropdown=================

const subsubtog = document.querySelectorAll(".sub-sub-drop");
const subSubMenu = document.getElementsByClassName("sub-sub-menu");

for (let y = 0; y < subsubtog.length; y++) {
  subsubtog[y].addEventListener("click", () => {
    subSubMenu[y].classList.toggle("show-sub-sub-menu");
  });
}

How It Works

  1. On Desktop:
    • Hovering over “Services” shows a dropdown menu.
    • Inside Services, you can also find a nested dropdown under “More”.
  2. On Mobile:
    • Clicking the hamburger icon () toggles the navigation menu.
    • Dropdown menus expand when you click on the arrow.
  3. Search Bar:
    • Clicking on the search icon shows the search bar.
    • Clicking the cross (×) hides the search bar again.

Benefits of This Navbar

  • Works perfectly on both desktop and mobile devices.
  • Lightweight – no external libraries required.
  • Stylish and modern dark theme with hover animations.
  • Easy-to-use search bar integration.
