Hiding content within live page

Hi,

Unless I’m having a moment, I can’t think how I can ‘hide’ specific content from a live page rather than deleting it – for the purpose of wanting to use it again.

Let me give you an example – a “current cars” page displaying iHover links to a Rolls Royce, A Ford and a BMW. The BMW sells and so I want to remove the BMW iHover element as I no longer have the stock. But I know I will probably get another BMW to sell next week so I don’t want to have to delete it to just recreate the same element next time. Is there a plugin to just hide/switch off certain elements or even rows?

Thanks.
