React component for draggable, efficiently rendering large lists with react-window

React Window Sortable

This library provides drag and drop sort functionality for very large lists.

This library wraps Brian Vaughn's excellent library react-window and adds drag and drop sorting.

Features

• Drag and drop to re-order list items
• Start drag with customized element or button
• Auto-scrolls when you drag something near the start or end of scroll view
• Can handle giant lists (+100 elements)
• Handles vertical lists only
• Very customizable

Install

# yarn
yarn add react-window-sortable

# npm
npm install --save react-window-sortable 

Usage

Fixed Size List (for rows of equal height) full example

<SortableFixedSizeList
    height={height}
    width={width}
    itemCount={n}
    itemSize={30}
    itemData={this.state.data}
    onSortOrderChanged={({originalIndex, newIndex}) => {
        move(this.state.data, originalIndex, newIndex);
        this.setState({
            data: this.state.data.slice(0),
        })
    }}
>
    {React.forwardRef(({data, index, style, onSortMouseDown}: ChildrenProps, ref: Ref<any>) => (
        <div ref={ref} style={style}>
            <button onMouseDown={onSortMouseDown}>drag handle</button>
            {data[index]}
        </div>
    ))}
</SortableFixedSizeList>

Variable Size List (for rows of variable height) full example

<SortableVariableSizeList
    height={height}
    width={width}
    itemCount={n}
    itemSize={index => index % 2 === 0 ? 30 : 50}
    itemData={this.state.data}
    onSortOrderChanged={({originalIndex, newIndex}: {originalIndex: number, newIndex: number}) => {
        move(this.state.data, originalIndex, newIndex);
        this.setState({
            data: this.state.data.slice(0),
        })
    }}
>
    {React.forwardRef(({data, index, style, onSortMouseDown}: ChildrenProps, ref: Ref<any>) => (
        <div ref={ref} style={style}>
            <button onMouseDown={onSortMouseDown}>drag handle</button>
            {data[index]}
        </div>
    ))}
</SortableVariableSizeList>

API

interface Props {
    // a render function to render list items
    children: React.ComponentType<ChildrenProps>;
    
    // the distance from the top or bottom of the scroll
    // window where autoscroll should kick in
    autoScrollWhenDistanceLessThan?: number;
    
    // the speed at which the autoscroll should go
    autoScrollSpeed?: number;
    
    // set the class name for the element that is being
    // moved by the cursor
    draggingElementClassName?: string;
    
    // set override styles on the style prop for the element
    // being moved by the cursor
    draggingElementStyle?: CSSProperties;
    
    // a custom element to render as a spot where the dragged
    // element can be dropped.
    dropElement?: any;
    
    // a callback when a sort has completed
    onSortOrderChanged(params: { originalIndex: number; newIndex: number }): void;
    
    // the height of the scroll window (px) 
    // you may want to use https://github.com/bvaughn/react-virtualized-auto-sizer
    // for this.
    height: number;
    
    // the width of the scroll window (px) 
    // you may want to use https://github.com/bvaughn/react-virtualized-auto-sizer
    // for this.
    width: number;
    
    // number of rows in data set
    itemCount: number;
    
    // height of the list item in px
    // for FixedSizedLists, this will be a constant.
    // for VariableSizedLists, this will be a lookup function
    itemSize: number | (index) => number;
    
    // the data to pass to the render function
    itemData: any[];
