If I remember correctly from my attempt at this (abandoned because it didn’t work for the web app), you need to make a ‘blank’ button on left and right sides to pad it.
I tried this tutorial, inspired by the primary introducer of this topic but, the link that is provided no longer works. Horizontal Scrolling - YouTube
Is there anyone who has a working horizontal scroller that I could study?
The new Beta Row component has that feature, not sure when will be published? @domhnallohanlon
