Improve example with a working loadMoreItems functionality

[Jimmy Kasprzak]

I think its great to have a working example, but it could use some improvements, like using the loadMoreItems functionality :)

I also think we can improve the ui of the example to make it looks like a bit better.

And if we agree it's needed, I'll work on it obviously :D
