Caption for fields in the FormLayout must be displayed on the left or right side, depending on the Locale setting of the Component.
In Right-to-Left languages (Hebrew, Arabic etc.), caption should come on the right side rather than on the left side.
Form layout does not support right-side captions.
I decided to write a more customizable form layout where you could position all the elements in any way you want to. I’ll get back to this thread if the idea works.
