react-virtualized-dnd is a React-based, fully virtualized drag-and-drop framework, enabling the the cross over of great user interaction and great performance. This project was made in response to the large amount of issues experienced trying to use virtualization libraries together with drag and drop libraries - react-virtualized-dnd does it all for you!

npm install --save react-virtualized-dnd


React-Virtualized-DnD utilizes a three part abstraction for drag and drop:

  • A DragDropContext, which controls the overall flow and events of the drag and drop.
  • Draggables, which are wrappers for the elements you want to drag around.
  • Droppables, which indicate a drop zone that Draggables can be dropped on, and create the virtualizing container. Draggables and Droppables can be organized in groups.

Droppables use an internal scrollbar to virtualize its children, and the DragDropContext offers the option to include an outer scrollbar that can be scrolled while dragging. Addtionally, a DragScrollBar component is also available, which is a simple scroll container that reacts to drags and scroll near its edges.

React-virtualized-dnd places a placeholder in droppables during drag, which is placed after the draggable element hovered over during drag. The placeholderId represents the id of the element it was placed after. On drag end, the DragDropContext returns the placeholderId.

Example code can be seen below. A live example can be found at:

import React, {Component} from 'react';
import ExampleBoard from 'react-virtualized-dnd';

class Example extends Component {
    render() {
      const name = 'my-group';
      const elemsToRender = [... your data here ...];
        return (
          <DragDropContext dragAndDropGroup={name} onDragEnd={this.onDragEnd.bind(this)} outerScrollBar={true}>
            <div className={'your-drag-container'}>
              {, index) => (
                <div className={'your-droppable-container'}>
                  <Droppable dragAndDropGroup={name} droppableId={elem.droppableId} key={elem.droppableId}>
                    { => (
                      <Draggable dragAndDropGroup={name} draggableId={}>
                        <div className='your-draggable-element'>

Documentation & API



dragAndDropGroupstringyesUnique identifier for the drag and drop group the context uses
outerScrollBarbooleannoEnables or disables global outer scrolling of the context (triggered by dragging)
scrollYSpeednumbernoCustom scroll speed for global page scrolling (y-axis)
scrollXSpeednumbernoCustom scroll speed for global page scrolling (x-axis)
autoScrollThresholdnumbernoDistance (in px) from the edges of the context where auto scroll is triggered during drag
scrollContainerHeightnumberno, yes with outerScrollBarHeight of the outer scrollable container
scrollContainerMinHeightnumbernoMinimum height of the outer scrollable container
onScrollfuncnoFunction fired when the DragDropContext's outer scrollbar scrolls. Returns {scrollX, scrollY}
onDragEndfunctionnoFunction fired on drag end with the source object, the droppableId of the destination, and the ID of the placeholder dropped on as params
onDragCancelfunctionnoFunction fired on drag end if the drop did not occur inside a droppable with the draggableId of the dragged element as params
onDragStartfunctionnoFunction fired on drag start with the draggableId of the dragged element as params

The placeholder ID can be used to determine where to place the dragged element on drag end. The placeholderID returns the string "END_OF_LIST" if dragged below the last element of a droppable.



dragAndDropGroupstringyesUnique identifier for the drag and drop group the context uses
draggableIdstringyesUnique identifier for the draggable
dragActiveClassstringnoCSS class applied to a draggable element during an active drag
disabledboolnoFlag to disabled dragging of element
minDragDistanceThresholdnumbernoMinimum pixels a drag should move, before registering new elements dragged over (for updating placeholder). Defaults to 5px, increase for better performance, but fewer scans
usePointerEventsboolnoFlag to enable pointer-event based implementation. Experimental for now.

Draggables will ignore drags started by clicking on any element with the "no-drag" css class. This can be used to control drag interactions with interactive elements, such as inputs or buttons.



dragAndDropGroupstringyesUnique identifier for the drag and drop group the context uses
droppableIdstringyesUnique identifier for the droppable
containerHeightNumberyesHeight of the virtualizing scroll container
placeholderStyleObjectnoCSS style object to style the placeholder during drag
enforceContainerMinHeightbooleannoForce height of the droppable to always minimally match the containerHeight
rowHeightNumbernoHeight of each row with borders. Default is 50px.
disableScrollbooleannoFlag to disable scrollbars. This disables virtualization as well
listHeaderHTML elementnoElement to use as header for a droppable list, to react to drops on top of the list.
listHeaderHeightNumberno (yes with listHeader)Height of the header element, necessary for calculations.
activeHeaderClassstringnoCSS class added to the header when an active drag is hovering over the list header
hideListbooleannohides all droppable elements in the list
dynamicElemHeightbooleannoFlag to indicate differing/dynamicly changing heights of children elements.*
virtualizationThresholdNumbernoMinimum number of elements in the list, before the virtualization kicks in. Useful if virtualizing very small lists produces flickers.
minElemHeightNumberno (yes with dynamicElemHeight)Minimum height of children elements. Necessary for calulating scrolling space.
customScrollbarscomponentnoComponent that uses forwardRef to generate scrollbars using react-custom-scrollbars
initialElemsToRenderNumbernoNumber of elements to initially render. Defaults to an optimistic guess about the number of elements that can fit in the viewport.

*Enabling dynamic element height fundamentally changes how the scrolling works, and requries some more complex logic that is completely separate from the normal virtualization. If you experience issues with it, I recommend using the static element height approach, or trying to make the rendered children more similar in size.



minHeightNumbernoMinimum Height of the Scroll Container
maxHeightNumbernoMaximum Height of the Scroll Container
autoScrollThresholdNumbernoDistance (in px) from the edges of the scroll container where auto scroll is triggered during drag
onScrollFunctionnoFunction fired when the Scrollbar scrolls. Returns {scrollX, scrollY}

Example Custom Scroll Bar

This component requires the usage of React's forwardRef to pass along the parent reference to the Scrollbars Element.
Please see react-custom-scrollbars for more information on how to customize a scrollbar.

import {Scrollbars} from 'react-custom-scrollbars';

const CustomScrollBars = React.forwardRef((props, ref) => {
    const {children,} = props;
    return (
        <Scrollbars ref={ref} renderThumbVertical={({style, ...props}) => <div style={{, backgroundColor: 'blue'}} {...props} />} {}>
