How to hide a field in a 2 column layout and keep the space reserved

I have a 2 column layout in a form. Field 1 determines whether field 2 is hidden or not. If it is hidden, field 3 is placed where field 2 would have been. I want to keep field 3 below field 1 regardless of whether field 2 is hidden or not. Is this possible?

Thank you! I was wondering if this is not possible without nested sections? I want to avoid this due to the added padding etc for each child section.
