I searched a lot to find a tutorial for drag & drop with jQuery alone (without UI), but due to the popularity of JQuery UI, all drag and drop features are based on JQuery UI.
Can anyone give me a hint how to make a basic Drag & Drop by JQuery standalone?
There are several plugins that you may use take a look at the following
