In this chapter, we will apply everything we've learned to build a practical application. We'll create a task organizer where users can drag items between different lists.

Initial Setup

The application will have the following features:

• Three lists: Pending Tasks, In Progress, and Completed.
• Users will be able to move tasks between these lists through drag and drop.

HTML Structure

html

Adding Functionality with JavaScript

We'll create an app.js file to manage the drag and drop interaction.

Defining Key Functions

javascript

Final Outcome

With this implementation, users can drag tasks between lists, moving them from one state to another.

Extension Exercise

Extend the organizer's functionality to include:

• Buttons to add new tasks.
• Data persistence using localStorage.
• A button to clear all lists.

Conclusion

In this chapter, we built an interactive task organizer using the Drag and Drop API. This practical project demonstrates how to combine basic and advanced skills to create a useful application.

In the next chapter, we will explore how to integrate Drag and Drop with other APIs, such as Canvas or Geolocation, for even more dynamic projects. Don't miss it!
