For instance, using a category menu to show different fireworks from a JSON file in your frontend can enhance user experience and streamline navigation. In this guide, we will explore the most efficient way to filter your product list using jQuery. We will break down the steps needed to implement this feature and provide examples you can use or adapt for your own projects. Understanding the Problem As a beginner to programming, you might have created a categories menu that isn’t functioning as expected.
