W3C WCAG Technique G210: Drag-and-drop cancellation
Documents that path-based drag-and-drop actions should be cancellable by releasing outside the target, moving the item back, confirming after drop, or providing undo, with attention to pointer and touch assistive technology constraints.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Drag and drop | Choose drag and drop when the design problem is moving an object from a source to a destination, position, group, or order. | Dragging starts only from the intended handle, object, or selected set, not from unrelated scroll or text-selection movement. | Supports cancellation, confirmation, and undo expectations for drag-and-drop actions. |
| Drag-and-drop upload | Choose drag-and-drop upload when dropping files from a desktop file manager is a common, useful shortcut. | Dragenter and dragover make the target visibly active only when the incoming data includes files. | W3C supports drag-and-drop cancellation and recovery expectations for pointer-based drag actions. |
| Touch gesture | Choose touch gesture when the design question is the recognition, feedback, fallback, and cancellation behavior of touch input itself. | The gesture starts only from the intended target or gesture region, not from unrelated content. | Supports cancellation, release-outside, confirmation, and undo expectations for path-based drag interactions. |
