This tutorial demonstrates building a drag-and-drop manipulator that inherits from PointerManipulator, tracks pointer events (down, move, up), and manages element positioning. The implementation includes two phases: dragging elements by calculating pointer offsets and applying them to element styles, then resolving drops by finding the nearest valid slot and snapping elements into place. The manipulator pattern keeps interaction logic self-contained and reusable across any visual element. ## Full article daily.dev links to this article rather than hosting it.
