Lazy Load List

Lazy Load List is a lightweight web package that loads items in lazy way to achieve high performance and better UX in large lists.

Rendering large lists makes the first load slow especially if items contain images, so this package split the list to small lists then it renders them one by one when scrolling to the end of the list..

you can notice the deference here:
