First... 200 fields on ONE table sounds like a design issue..   When you say "cascaded views"... it sounds like you are requesting an "expandable" view..  That would be a nice UI control to have.. :) 

Not fully understanding your use case... one approach would be to add some checkboxes / dropdowns / what have you... and then put logic into the various "Display field only if" formulas... .. Basically "hiding" the field under a section .. and then displaying the fields under the section.

I think @wynand talking about Edit Fields screen...
