I was wondering if there is a supported way to dynamically show/hide the prompt, input and help fields for a setting in a .page file under Javascript control? I have tried adding <span>...</span> type constructs around the setting but that does not work as the standard processing of a .page file ends up putting the <span> and </span> tags into different html elements thus rendering them ineffective.

The reason I want to do this is to hide settings that are not relevant if previous setting are set to a particular value as I feel that provides a friendlier and more intuitive user experience. At the moment all I have managed to do is disable the input field for such settings. If there is a better way to handle this I am open to ideas?

Just to update this in case someone else has a similar problem it seems to work if you use a <div> element instead of a <span> one.
