HTML Drag and Drop interfaces enable applications to use drag-and-drop features in browsers. The user may select draggable elements with a mouse, drag those elements to a droppable element, and drop them by releasing the mouse button. A translucent representation of the draggable elements follows the pointer during the drag operation.

For web sites, extensions, and XUL applications, you can customize which elements can become draggable, the type of feedback the draggable elements produce, and the droppable elements.

This overview of HTML Drag and Drop includes a description of the interfaces, basic steps to add drag-and-drop support to an application, and an interoperability summary of the interfaces.

Drag Events
HTML drag-and-drop uses the DOM event model and drag events inherited from mouse events. A typical drag operation begins when a user selects a draggable element, drags the element to a droppable element, and then releases the dragged element.

During drag operations, several event types are fired, and some events might fire many times, such as the drag and dragover events.

Each drag event type has an associated global event handler:
