In today's digital world, having a responsive navigation bar is essential for a user-friendly and smooth browsing experience. Navigation bars provide a quick and easy way for users to navigate through a website's pages, making them a crucial element of web design. Additionally, dropdown menus have become increasingly popular in recent years, allowing for a more organized and streamlined user experience. In this blog post, we will explore how to create a responsive navigation bar with a dropdown menu using JavaScript. We will walk through the steps of setting up the HTML and CSS for the navigation bar, adding the dropdown menu, and implementing the JavaScript code to make the dropdown menu functional. By the end of this tutorial, you will better understand how to create a responsive and user-friendly navigation bar that includes a dropdown menu using JavaScript.

This project has a navigation menu as you can see in the image above. There is a logo named incoder in the left section. Then there are links in the center link named HTML & CSS has a Dropdown. When you click on it dropdown menu will be opened. There is a search button a window will be opened when you click on it. Unable to understand what am I saying then check the live demo.
