is removal of fields reversible?

It seems like using the decorator approach, if we remove an item from the schema object in our wrapper class, then pass that filtered schema down to the mozilla form, we will have lost our component. If we use this approach, we might then need to have some separate state object that represents deleted schema items?

Or maybe instead of deleting the form items we just add/remove a CSS class that hides the component's visibility?

closed because full schema is stored in state.
