Horizontal Scroll via viewport width settings
As we know web design aesthetics evolve day by day. And for this purpose Adobe XD is still following conventional ways of designing. I wanna highlight very basic and important feature that must be include in Adobe XD. I am sharing an example that will help your engineer to demonstrate this feature in well mannered way.
As you can see user can easily scroll horizontally. This feature is slightly different from existing horizontal scroll group because we can only click and drag with that feature.
I hope you will get my point. I can assist to you more if required.
