javascript drag and drop of the elements into boxes and post requests

I'm looking for someone to create a javascript drag and drop system that allows dragging of elements into boxes and posts requests. This drag and drop system should be responsive, allowing users to interact easily with the interface. The system should include two columns in total. Finally, the system should be able to track the number of elements dragged into boxes. Freelancers should have a solid understanding of HTML, CSS and Javascript, as well as have experience in building drag and drop systems. Thank you for considering my project!
