How do I create a limited overview and a more detailed entry when they click view?

 So I am working on http://proaccessconsultants.com/new/ and I have about 20 different columns for each entry. I only want to show the ones currently up, but when they hit view I want them to be able to see the other categories. Is there a simple way to go about doing that?
