jQuery UI - simple scroll - scroll-content width

jQuery UI - simple scroll - scroll-content width

I need to populate the scroller with dynamic data. That means that I might have different widths of the
scroll-content which by default has a value of 2440px.

Can scroll-content have automatic width based on how many items there are? Pleas let me know.

Best Regards,
Krystian
