How can several fields be added to one line?

I am trying to find containers so that I can add multiple Form controls on the same line. I just can't find a way to do it. This should be obvious.

As far as I understood the question, it looks like you need to add several form fields in one line. To do so, please try to "Shrink" the fields as shown on the screenshot below:

If you did mean something else, please clarify your question, so we could assist you better.

Hope this helps!
