Infinite Scroll

Infinite Scroll with Conveyer.
The conveyer can be used in combination with other components.

  • The InfiniteScroll module uses InfiniteGrid.
  • If it is combined with other components, it is difficult to get a ref. You can initialize it by setting autoInit to false and setting the ref directly.
