For most question type you can make fields sit side by side as two columns by:

  1. Going to Configure to the right of the question
  2. Scrolling to the bottom to turn the “make one of two columns” toggle on
  3. Doing the same for the other question you want to be included (it must be the question immediately before or after)

Note that questions will only be shown in columns on devices with larger screens. When the screen is too small, the questions will fall back to a single column.
