It is possible to have infinite scrolling pages inside an overflow element.
First define a container element.
<div id="scroller">
<div class="item">Item 1</div>
<div class="item">Item 2</div>
<!-- more items -->
</div>
Then configure the overflow using css. Don't forget to give the element a fixed height.
#scroller {
overflow: scroll;
height: 200px;
}
Then configure the element as scroll container.
let ias = new InfiniteAjaxScroll('#scroller', {
scrollContainer: '#scroller'
});
