react-window

React component responsible for rendering a row.

This component will receive an index and style prop by default.
Additionally it will receive prop values passed to rowProps.

ℹ️ The prop types for this component are exported as RowComponentProps

Number of items to be rendered in the list.

Row height; the following formats are supported:

• number of pixels (number)


• percentage of the grid's current height (string)


• function that returns the row height (in pixels) given an index and cellProps


• dynamic row height cache returned by the useDynamicRowHeight hook

⚠️ Dynamic row heights are not as efficient as predetermined sizes.
It's recommended to provide your own height values if they can be determined ahead of time.

Additional props to be passed to the row-rendering component.
List will automatically re-render rows when values in this object change.

⚠️ This object must not contain ariaAttributes, index, or style props.

CSS class name.

Optional CSS properties.
The list of rows will fill the height defined by this style.

Additional content to be rendered within the list (above cells).
This property can be used to render things like overlays or tooltips.

Default height of list for initial render.
This value is important for server rendering.

Ref used to interact with this component's imperative API.

This API has imperative methods for scrolling and a getter for the outermost DOM element.

ℹ️ The useListRef and useListCallbackRef hooks are exported for convenience use in TypeScript projects.

Callback notified when the List's outermost HTMLElement resizes.
This may be used to (re)scroll a row into view.

Callback notified when the range of visible rows changes.

How many additional rows to render outside of the visible area.
This can reduce visual flickering near the edges of a list when scrolling.

Can be used to override the root HTML element rendered by the List component.
The default value is "div", meaning that List renders an HTMLDivElement as its root.

⚠️ In most use cases the default ARIA roles are sufficient and this prop is not needed.

React component responsible for rendering a cell.

This component will receive an index and style prop by default.
Additionally it will receive prop values passed to cellProps.

ℹ️ The prop types for this component are exported as CellComponentProps

Additional props to be passed to the cell-rendering component.
Grid will automatically re-render cells when values in this object change.

⚠️ This object must not contain ariaAttributes, columnIndex, rowIndex, or style props.

Number of columns to be rendered in the grid.

Column width; the following formats are supported:

• number of pixels (number)


• percentage of the grid's current width (string)


• function that returns the column width (in pixels) given an index and cellProps

Number of rows to be rendered in the grid.

Row height; the following formats are supported:

• number of pixels (number)


• percentage of the grid's current height (string)
