When dragging an item, you need to detect valid drop targets and provide visual feedback (e.g., highlight the drop zone). Manual detection using drag events is error‑prone, especially with nested elements.
DropTarget detects when a dragged element enters, leaves, or hovers over a drop zone. It works with HTML5 native drag & drop
and provides callbacks for onDragEnter, onDragLeave, and onDrop. This demo uses the library’s
implementation (with a fallback) to accept or reject drops.
