When using Row style: Stripes you will get parallax option. Scroll options tab down until you see the “Enable parallax” checkbox (see fig. 3):
After checking it, additional “Parallax speed” input will be revealed. “1” value equals normal scrolling speed (no parallax effect). For a better result, keep this value in range from 0.3 to 0.7.
