Introduction

If you're building a website with a multi-level dropdown menu and using Bootstrap for styling, you might want to add some dynamic effects to enhance user experience. In this post, we are going to solve the common issue of making dropdowns feel more interactive by adding a stylish fade effect. A well-designed dropdown menu can make your navigation clearer and more enjoyable for your users, so follow along to create that smooth effect.

Problem Statement

You have a multi dropdown menu with submenus set up in a vertical navbar using Bootstrap 3 and jQuery. You want to implement a fade effect that animates each list item from bottom to top when the menu is activated. The initial approach of simply adjusting the CSS properties did not yield the desired results. Let's address this and make that dropdown pop!
