Hi,
Yes, the slider will work without the scrollbar as well.
From devices with a touchscreen, you can simply swipe. Also, you should be able to use a laptop’s touchpad, and a Mac mouse to slide.
In case these are not available then yes, you can only slide using the scrollbar.
We do have plans to add arrows for triggering the sliding effect, but those are not yet available.
Hope this helps,
Roni
