Set Unity UI scroll view elements height properly in different resolutions

Hi,

I have a UI with a scroll view elements that I want to adapt to different resolutions. I'm using content size filter + horizontal layout group on the content GameObject and that's working fine as far as the laying of the elements.

However when I resize the window to different ratios my elements resize out of the screen:

The container of the scroll view is resizing properly, however I'm unable to find a technique to resize the elements themselves properly. I tried playing all day with the min/preferred parameters but couldn't make it work right...

Any ideas?

Cheers!
