Freeze right side column in gallery

[mmchx]

Hi all,

The app that I created, I don't want it to responsive and It has many columns to show in the gallery.

So, I just found this article https://michalsacewicz.com/power-apps-horizontal-scroll-in-a-vertical-gallery-with-freeze-panes-effe...

But seems like I need to turn off the "scale to fit" first to do something like Michal.

This is what I have done. I made a Header as Group because I want to put the icon on the header. 

And I tried to make the right-side column/icon freeze. It doesn't work as Michael did.  I know that the easiest way is put the icon on the left side but on the right-side users seem to prefer it.

How can I do something like the image below?

Hello @mmchx ,

What doesn't work in your app? Is the slider properly moving the columns? Are the icons staying in place or are they moving along the columns? Are columns aligned with their header?
