My script has been rejected

Hi, everybody. My decision was rejected, but I don’t understand why. Can someone tell me?
Link to my solution - https://www.elcore.ru/envato/magicform/

With respect this is not enough for here.

Popular form builder items have vastly more features and flexibility as well as often containing their own drag and drop interface

Thanks a lot. I focused on solutions that are already present on the site.
