Drag & Drop
Drag and drop lets people move, reorder, or transfer an item directly. It must show when the item is picked up and where it can land.
pointer events + keyboard alternativeA real example
A task card shows a preview when it's picked up. Valid spots open a gap, and dropping the card confirms its new order.

- 02Property change
- 03Timing model
- 04Reduced-motion result
Use it when
Use it when moving an item in space is faster and the result can be undone.
Do not use it when
Never make drag and drop the only method. Add keyboard support and clear move controls.

Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.
Outcome: Use or define Drag & Drop to make the visual experience clear and easy to use. User context: A task card shows a preview when it's picked up. Valid spots open a gap, and dropping the card confirms its new order. Design concept to apply: Drag & Drop. Why it fits: Use it when moving an item in space is faster and the result can be undone. Do not use it when: Never make drag and drop the only method. Add keyboard support and clear move controls. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): The standard covers only the listed scope. It does not choose the visual style, product decision, or Vibulary example. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.
