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.

Example:

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.

Thanks
