The act of picking an item or chunk of text, moving it, and then placing it in another location is known as drag-and-drop functionality. With a mouse, the user may pick draggable items, drag them to a droppable element, then drop them by releasing the mouse button. To implement drag and drop functionality in conventional HTML4, developers had to utilize difficult JavaScript programming or other JavaScript frameworks like jQuery. HTML 5 introduced a Drag and Drop (DnD) API that delivers native DnD support to the browser.
