react-list-any-height

React scroll list for item with any height.

Example: https://wangtao0101.github.io/react-list-any-height/

Motivation

react virtualized and react-infinite can only handle list with fixed height, but that may not always be the case.

Install

npm install react-list-any-height --save
yarn add react-list-any-height

Basic Use

Elements of Any Height

As we don't know the height of all row before the row had been rendered, we figure out the height of contianer by using minRowHeight.

<AnyHeight
    dataSource={dataSource}
    minRowHeight={100}
    rowRender={(index, style) => (
        <div className="hover-row" style={style)}></div>
    )}
/>

How to work

We figure out the origin height of contianer by using minRowHeight. After you scroll and the more row will be rendered, we using new heights to update component in next scrolling.

Note on Smooth Scrolling

minRowHeight should be set reasonable, otherwise if you scroll to end fastly and then you scroll to up slowly, then page will jump.

Api

dataSource

the data array, isRequired

minRowHeight

The minimum height of all rows, isRequired

height

The height of scrolling contianer, default to 300.

preloadBatchSize

The items rendered out of contianer, default to 5.

style

The style of contianer, default to style: { width: '100%' }.

rowStyle

The style of row

rowRender

A function for rendering a row, isRequired

timeScrollStateLastsForAfterUserScrolls(same as react-infinite)

Defaults to 150 (in milliseconds). On Apple and some other devices, scroll is inertial. This means that the window continues to scroll for several hundred milliseconds after an onScroll event is fired. To prevent janky behavior, we do not want pointer-events to reactivate before the window has finished moving. Setting this parameter causes the Infinite component to think that the user is still scrolling for the specified number of milliseconds after the last onScroll event is received.
