In the latest version of the Universal GUI, We are able to have responsive fields (provided that field width and label width are empty). Responsive fields that resizes its own width depending on the size of the screen(Width).

(Is it possible to have an option or do we have an option) in the SF->Subjects->Default->Components    ->Form, where the field automatically resizes depending on the height of the screen?
or Is this already possible by applying in a different way other than in Subjects?

Currently In my knowledge we have "Field height in positions"  in Subjects ,to add height on a field that can contain a paragraph of strings, in SF, But this is a fixed size as shown in my GIF example.
