A single form is already used to contain those fields. Even though visually they may appear separate those controls are represented as a single form within the HTML. Therefore, this comes down to a HTML/CSS issue more so than PHP. The only reason you would need to modify the PHP/HTML would be if the intended design requires it. Though it looks like ti would be possible to change the design with CSS alone. It all depends on how you want the controls to display. A single line really wouldn’t work well considering all the different screen resolutions out there. If you were to put that all on one line it would undoubtably looked crammed on some screen widths.
