Can't add draggable element on drop area

[nimachitgar]

I am trying to drop an element into a dropzone using the draggable element plugin but the element keeps going back to its place instead of dropping on the dropzone. (Below you can see what happens) I did not use a workflow as I presume that the plugin lets you automatically add a group in a dropzone?

Does anyone know how I can fix this? Below you can see my settings for both the dropzone element and draggable element.

I am no expert on this but I have used the drag and drop in my app. From my understanding, you need to make the changes using workflows. You could probably do that using states

If dropped in this area, minus item from repeating group data, and add line item to dropped area state.

Indeed, your solution has worked for me! Thanks a lot!
