How to move field to the Left when other field at the left are blank

Question

I have two frames in one frame and they are oriented horizontally(next to each other). I want to move the second field to the left, when the left field is empty or null. I have tried out using float but that was only helpful when I wanted to move fields to the top. How can I do this?
