Minor Changes

• #1271 bc588c7 Thanks @clauderic! - Introduce bypassActivationConstraint() option for PointerSensor, MouseSensor and TouchSensor. This optional argument can be used to conditionally bypass activation constraints. An example use-case would be to bypass activation constraints when the activator event target is the activatorNode of a draggable source.

  useSensor(PointerSensor, {
    activationConstraint: {
      delay: 250,
      tolerance: 5,
    },
    bypassActivationConstraint({event, activeNode}) {

Patch Changes

Patch Changes

• #772 e97cb1f Thanks @clauderic! - The ARIA live region element used for screen reader announcements is now positioned using position: fixed instead of position: absolute. As of @dnd-kit/core^6.0.0, the live region element is no longer portaled by default into the document.body. This change was introduced in order to fix issues with portaled live regions. However, this change can introduce visual regressions when using absolutely positioned elements, since the live region element is constrained to the stacking and position context of its closest positioned ancestor. Using fixed position ensures the element does not introduce visual regressions.

Patch Changes

• #769 8e3599f Thanks @clauderic! - Fixed an issue with the containerNodeRect that is exposed to modifiers having stale properties (top, left, etc.) when its scrollable ancestors were scrolled.

• #769 53cb962 Thanks @clauderic! - Fixed a regression with scrollable ancestors detection.

  The scrollable ancestors should be determined by the active node or the over node exclusively. The draggingNode variable shouldn't be used to detect scrollable ancestors since it can be the drag overlay node, and the drag overlay node doesn't have any scrollable ancestors because it is a fixed position element.

Patch Changes

• #759 e5b9d38 Thanks @clauderic! - Fixed a regression with the default drop animation of <DragOverlay> for consumers using React 18.

Major Changes

• #746 4173087 Thanks @clauderic! - Accessibility related changes.

  Regrouping accessibility-related props

  Accessibility-related props have been regrouped under the accessibility prop of <DndContext>:

  <DndContext
  - announcements={customAnnouncements}
  - screenReaderInstructions={customScreenReaderInstructions}
  + accessibility={{
  +  announcements: customAnnouncements,
  +  screenReaderInstructions: customScreenReaderInstructions,
  + }}
  

  This is a breaking change that will allow easier addition of new accessibility-related features without overloading the props namespace of <DndContext>.

  Arguments object for announcements

  The arguments passed to announcement callbacks have changed. They now receive an object that contains the active and over properties that match the signature of those passed to the DragEvent handlers (onDragStart, onDragMove, etc.). This change allows consumers to read the data property of the active and over node to customize the announcements based on the data.

  Example migration steps:

  export const announcements: Announcements = {
  -  onDragStart(id) {
  +  onDragStart({active}) {
  -    return `Picked up draggable item ${id}.`;
  +    return `Picked up draggable item ${active.id}.`;
    },
  -  onDragOver(id, overId) {
  +  onDragOver({active, over}) {
  -    if (overId) {
  +    if (over) {
  -      return `Draggable item ${id} was moved over droppable area ${overId}.`;
  +      return `Draggable item ${active.id} was moved over droppable area ${over.id}.`;
      }
  
  -    return `Draggable item ${id} is no longer over a droppable area.`;
  +    return `Draggable item ${active.id} is no longer over a droppable area.`;
    },
  };
  

  Accessibility-related DOM nodes are no longer portaled by default

  The DOM nodes for the screen reader instructions and announcements are no longer portaled into the document.body element by default.

  This change is motivated by the fact that screen readers do not always announce ARIA live regions that are rendered on the document.body. Common examples of this include when rendering a <DndContext> within a <dialog> element or an element that has role="dialog", only ARIA live regions rendered within the dialog will be announced.

  Consumers can now opt to render announcements in the portal container of their choice using the container property of the accessibility prop:

  <DndContext
  + accessibility={{
  +  container: document.body,
  + }}
  

• #733 035021a Thanks @clauderic! - The <DragOverlay> component's drop animation has been refactored, which fixes a number of bugs with the existing implementation and introduces new functionality.

  What's new?

  Scrolling the draggable node into view if needed

  The drop animation now ensures that the the draggable node that we are animating to is in the viewport before performing the drop animation and scrolls it into view if needed.

  Changes to the dropAnimation prop

  The dropAnimation prop of <DragOverlay> now accepts either a configuration object or a custom drop animation function.

  The configuration object adheres to the following shape:

  interface DropAnimationOptions {
    duration?: number;
    easing?: string;
    keyframes?: DropAnimationKeyframeResolver;
    sideEffects?: DropAnimationSideEffects;
  }
  

  The default drop animation options are:

  const defaultDropAnimationConfiguration: DropAnimationOptions = {
    duration: 250,
    easing: 'ease',
    keyframes: defaultDropAnimationKeyframes,
    sideEffects: defaultDropAnimationSideEffects({
      styles: {
        active: {
          opacity: '0',
        },
      },
    }),
  };
  

  The keyframes option allows consumers to override the keyframes of the drop animation. For example, here is how you would add a fade out transition to the drop animation using keyframes:

  import {CSS} from '@dnd-kit/utilities';
  
  const customDropAnimation = {
    keyframes({transform}) {
      return [
        {opacity: 1, transform: CSS.Transform.toString(transform.initial)},
        {opacity: 0, transform: CSS.Transform.toString(transform.final)},
      ];
    },
  };
  

  The dragSourceOpacity option has been deprecated in favour of letting consumers define arbitrary side effects that should run before the animation starts. Side effects may return a cleanup function that should run when the drop animation has completed.

  type CleanupFunction = () => void;
  
  export type DropAnimationSideEffects = (
    parameters: DropAnimationSideEffectsParameters
  ) => CleanupFunction | void;
  

  Drop animation side effects are a powerful abstraction that provide a lot of flexibility. The defaultDropAnimationSideEffects function is exported by @dnd-kit/core and aims to facilitate the types of side-effects we anticipate most consumers will want to use out of the box:

  interface DefaultDropAnimationSideEffectsOptions {
    // Apply a className on the active draggable or drag overlay node during the drop animation
    className?: {
      active?: string;
      dragOverlay?: string;
    };
    // Apply temporary styles to the active draggable node or drag overlay during the drop animation
    styles?: {
      active?: Styles;
      dragOverlay?: Styles;
    };
  }
  

  For advanced side-effects, consumers may define a custom sideEffects function that may optionally return a cleanup function that will be executed when the drop animation completes:

  const customDropAnimation = {
    sideEffects({active}) {
      active.node.classList.add('dropAnimationInProgress');
      active.node.animate([{opacity: 0}, {opacity: 1}], {
        easing: 'ease-in',
        duration: 250,
      });
  
      return () => {
        // Clean up when the drop animation is complete
        active.node.classList.remove('dropAnimationInProgress');
      };
    },
  };
  

  For even more advanced use-cases, consumers may also provide a function to the dropAnimation prop, which adheres to the following shape:

  interface DropAnimationFunctionArguments {
    active: {
      id: UniqueIdentifier;
      data: DataRef;
      node: HTMLElement;
      rect: ClientRect;
    };
    draggableNodes: DraggableNodes;
    dragOverlay: {
      node: HTMLElement;
      rect: ClientRect;
    };
    droppableContainers: DroppableContainers;
    measuringConfiguration: DeepRequired<MeasuringConfiguration>;
    transform: Transform;
  }
  
  type DropAnimationFunction = (
    args: DropAnimationFunctionArguments
  ) => Promise<void> | void;
  

  Bug fixes

  • The <DragOverlay> now respects the measuringConfiguration specified for the dragOverlay and draggable properties when measuring the rects to animate to and from.
  • The <DragOverlay> component now supports rendering children while performing the drop animation. Previously, the drag overlay would be in a broken state when trying to pick up an item while a drop animation was in progress.

  Migration steps

  For consumers that were relying on the dragSourceOpacity property in their dropAnimation configuration:

  + import {defaultDropAnimationSideEffects} from '@dnd-kit/core';
  
  const dropAnimation = {
  - dragSourceOpacity: 0.5,
  + sideEffects: defaultDropAnimationSideEffects({
  +   styles : {
  +     active: {
  +       opacity: '0.5',
  +     },
  +   },
  +  ),
  };
  

• #745 5f3c700 Thanks @clauderic! - The keyboard sensor now keeps track of the initial coordinates of the collision rect to provide a translate delta when move events are dispatched.

  This is a breaking change that may affect consumers that had created custom keyboard coordinate getters.

  Previously the keyboard sensor would measure the initial rect of the active node and store its top and left properties as its initial coordinates it would then compare all subsequent move coordinates to calculate the delta.

  This approach suffered from the following issues:

  • It didn't respect the measuring configuration defined on the <DndContext> for the draggable node
  • Some consumers re-render the active node after dragging begins, which would lead to stale measurements
  • An error had to be thrown if there was no active node during the activation phase of the keyboard sensor. This shouldn't be a concern of the keyboard sensor.
  • The currentCoordinates passed to the coordinate getter were often stale and not an accurate representation of the current position of the collision rect, which can be affected by a number of different variables, such as modifiers.

• #755 33e6dd2 Thanks @clauderic! - The UniqueIdentifier type has been updated to now accept either string or number identifiers. As a result, the id property of useDraggable, useDroppable and useSortable and the items prop of <SortableContext> now all accept either string or number identifiers.

  Migration steps

  For consumers that are using TypeScript, import the UniqueIdentifier type to have strongly typed local state:

  + import type {UniqueIdentifier} from '@dnd-kit/core';
  
  function MyComponent() {
  -  const [items, setItems] = useState(['A', 'B', 'C']);
  +  const [items, setItems] = useState<UniqueIdentifier>(['A', 'B', 'C']);
  }
  

  Alternatively, consumers can cast or convert the id property to a string when reading the id property of interfaces such as Active, Over, DroppableContainer and DraggableNode.

  The draggableNodes object has also been converted to a map. Consumers that were reading from the draggableNodes property that is available on the public context of <DndContext> should follow these migration steps:

  - draggableNodes[someId];
  + draggableNodes.get(someId);
  

Minor Changes

• #748 59ca82b Thanks @clauderic! - Automatic focus management and activator node refs.

  Introducing activator node refs

  Introducing the concept of activator node refs for useDraggable and useSortable. This allows @dnd-kit to handle common use-cases such as restoring focus on the activator node after dragging via the keyboard or only allowing the activator node to instantiate the keyboard sensor.

  Consumers of useDraggable and useSortable may now optionally set the activator node ref on the element that receives listeners:

  import {useDraggable} from '@dnd-kit/core';
  
  function Draggable(props) {
    const {
      listeners,
      setNodeRef,
  +   setActivatorNodeRef,
    } = useDraggable({id: props.id});
  
    return (
      <div ref={setNodeRef}>
        Draggable element
        <button
          {...listeners}
  +       ref={setActivatorNodeRef}
        >
          :: Drag Handle
        </button>
      </div>
    )
  }
  

  It's common for the activator element (the element that receives the sensor listeners) to differ from the draggable node. When this happens, @dnd-kit has no reliable way to get a reference to the activator node after dragging ends, as the original event.target that instantiated the sensor may no longer be mounted in the DOM or associated with the draggable node that was previously active.

  Automatically restoring focus

  Focus management is now automatically handled by @dnd-kit. When the activator event is a Keyboard event, @dnd-kit will now attempt to automatically restore focus back to the first focusable node of the activator node or draggable node.

  If no activator node is specified via the setActivatorNodeRef setter function of useDraggble and useSortable, @dnd-kit will automatically restore focus on the first focusable node of the draggable node set via the setNodeRef setter function of useDraggable and useSortable.

  If you were previously managing focus manually and would like to opt-out of automatic focus management, use the newly introduced restoreFocus property of the accessibility prop of <DndContext>:

  <DndContext
    accessibility={{
  +   restoreFocus: false
    }}
  

• #751 a52fba1 Thanks @clauderic! - Added the aria-disabled attribute to the attribtues object returned by useDraggable and useSortable. The value of the aria-disabled attribute is populated based on whether or not the disabled argument is passed to useDraggble or useSortable.

• #741 40707ce Thanks @clauderic! - The auto scroller now keeps track of the drag direction to infer scroll intent. By default, auto-scrolling will now be disabled for a given direction if dragging in that direction hasn't occurred yet. This prevents accidental auto-scrolling when picking up a draggable item that is near the scroll boundary threshold.

• #660 a41e5b8 Thanks @clauderic! - Fixed a bug with the delta property returned in onDragMove, onDragOver, onDragEnd and onDragCancel. The delta property represents the transform delta since dragging was initiated, along with the scroll delta. However, due to an oversight, the delta property was actually returning the transform delta and the current scroll offsets rather than the scroll delta.

  This same change has been made to the scrollAdjustedTranslate property that is exposed to sensors.

• #750 bf30718 Thanks @clauderic! - The useDndMonitor() hook has been refactored to be synchronously invoked at the same time as the events dispatched by <DndContext> (such as onDragStart, onDragOver, onDragEnd).

  The new refactor uses the subscribe/notify pattern and no longer causes re-renders in consuming components of useDndMonitor() when events are dispatched.

• #660 a41e5b8 Thanks @clauderic! - The activeNodeRect and containerNodeRect are now observed by a ResizeObserver in case they resize while dragging.

• #660 a41e5b8 Thanks @clauderic! - Improved useDraggable usage without <DragOverlay>:

  • The active draggable now scrolls with the page even if there is no <DragOverlay> used.
  • Fixed issues when re-ordering the active draggable node in the DOM while dragging.

• #660 77e3d44 Thanks @clauderic! - Fixed an issue with useDroppable hook needlessly dispatching SetDroppableDisabled actions even if the disabled property had not changed since registering the droppable.

• #749 188a450 Thanks @clauderic! - The onDragStart, onDragMove, onDragOver, onDragEnd and onDragCancel events of <DndContext> and useDndMonitor now expose the activatorEvent event that instantiated the activated sensor.

• #733 035021a Thanks @clauderic! - The KeyboardSensor now scrolls the focused activator draggable node into view if it is not within the viewport.

• #733 035021a Thanks @clauderic! - By default, @dnd-kit now attempts to compensate for layout shifts that happen right after the onDragStart event is dispatched by scrolling the first scrollable ancestor of the active draggable node.

  The autoScroll prop of <DndContext> now optionally accepts a layoutShiftCompensation property to control this new behavior:

  interface AutoScrollOptions {
    acceleration?: number;
    activator?: AutoScrollActivator;
    canScroll?: CanScroll;
    enabled?: boolean;
    interval?: number;
  + layoutShiftCompensation?: boolean | {x: boolean, y: boolean};
    order?: TraversalOrder;
    threshold?: {
      x: number;
      y: number;
    };
  }
  

  To enable/disable layout shift scroll compensation for a single scroll axis, pass in the following autoscroll configuration to <DndContext>:

  <DndContext
    autoScroll={{layoutShiftCompensation: {x: false, y: true}}}
  >
  

  To completely disable layout shift scroll compensation, pass in the following autoscroll configuration to <DndContext>:

  <DndContext
    autoScroll={{layoutShiftCompensation: false}}
  >
  

• #672 10f6836 Thanks @clauderic! - The measureDroppableContainers method now properly respects the MeasuringStrategy defined on <DndContext /> and will not measure containers while measuring is disabled.

• #656 c1b3b5a Thanks @clauderic! - Fixed an issue with collision detection using stale rects. The droppableRects property has been added to the CollisionDetection interface.

  All built-in collision detection algorithms have been updated to get the rect for a given droppable container from droppableRects rather than from the rect.current ref:

  - const rect = droppableContainers.get(id).rect.current;
  + const rect = droppableRects.get(id);
  

  The rect.current ref stored on DroppableContainers can be stale if measuring is scheduled but has not completed yet. Collision detection algorithms should use the droppableRects map instead to get the latest, most up-to-date measurement of a droppable container in order to avoid computing collisions against stale rects.

  This is not a breaking change. However, if you've forked any of the built-in collision detection algorithms or you've authored custom ones, we highly recommend you update your use-cases to avoid possibly computing collisions against stale rects.

Patch Changes

• #742 7161f70 Thanks @clauderic! - Fallback to initial rect measured for the active draggable node if it unmounts during initialization (after onDragStart is dispatched).

• #749 5811986 Thanks @clauderic! - The Data and DataRef types are now exported by @dnd-kit/core.

• #699 e302bd4 Thanks @JuAn-Kang! - Export DragOverlayProps for consumers.

• 750d726 Thanks @clauderic! - Fixed a bug in the KeyboardSensor where it would not move the draggable on the horizontal axis if it could fully scroll to the new vertical coordinates, and would not move the draggable on the vertical axis if it could fully scroll to the new horizontal coordinates.

• #660 e6e242c Thanks @clauderic! - The KeyboardSensor was updated to use scrollTo instead of scrollBy when it is able to fully scroll to the new coordinates returned by the coordinate getter function. This resolves issues that can happen with scrollBy when called in rapid succession.
