    right: "..."
}

onActive

When provided, this is called with the index of the item that the user has either moused over or navigated to with their keyboard.

function

(index) => {}

onClickItem

When supplied, this function will be called with an event object which includes an 'item' property containing the data value associated with the clicked item and an 'index' property containing the index in 'data' of the clicked item. You should not include interactive elements, like Anchor or Button inside 'primaryKey' or 'secondaryKey' as that can cause confusion with overlapping interactive elements.

function

({ item, index }) => {}

onMore

Use this to indicate that 'data' doesn't contain all that it could. It will be called when all of the data items have been rendered. This might be used when the total number of items that could be retrieved is more than you'd want to load into the browser. 'onMore' allows you to lazily fetch more from the server only when needed.

function

() => {}

onOrder

Use this to indicate that the user should be allowed to re-order the data items. This cannot be used with 'paginate' or 'onClickItem'. The function will be called with the array of items in their new order when the user moves items via drag and drop or the move up/down controls.

React/DOM Properties

At its core, the List component is a regular <ol> element. Thus, both DOM and React properties, methods, and events are accessible. To read up on all of the possible DOM attributes and types available for ol elements, check out this MDN Web Documents page. To learn more about DOM events and methods, you can read more on the MDN Web Events documentation page.

Also, feel free to read about the types of React events available, or see how DOM attributes change in React. Working in tandem with Styled Components, you also have access to the as property.
