You can replace the pagination with infinite scrolling. It is when customers start searching, the Search Results Widget shows only a part of the search results. But as the customers scroll down to the end of the page, the widget loads more results that extend the previous ones.

2. Set the Enable infinite scrolling toggle to ON.
3. Apply the changes.

That’s it. It is now infinite scrolling is enabled in the Search Results Widget.
