Drag-and-drop
Drag-and-drop uses HTML5 code to facilitate the layout of content.
Drag sources and drop targets do not need any JavaScript library. Some convenience functions are provided in the i$.dnd API. For example, with drag-and-drop, we can drag an item, such as a portlet or content item from the toolbar on the page. Or we can drag an item from one position on the page to another position.
