Yes it is, we support adding fields "side by side", when you have a field selected there is a "+" sign to the right that will bring up a vertical form field toolbar which you can add an adjacent field. You can also use the context (right click) menu and select "Add item beside". You can also move your existing fields next to one another by dragging and dropping the field, a blue bar appears where the field would drop and if you drag along the right side of the page it will offer to drop the field adjacent others.
As an example, several of the Templates have the fields in rows.
We do not offer formatting in actual columns, but you can resize fields to accomplish a two column look with side by side fields.
