When I visit web sites I see pages that have some text followed by a control that says 'Read More' and when you click on that link the rest of the text appears. I've been trying to search for that type of control but I really don't know how to word it. I'm working on my church website and this would come in handy in a number of places. What should I enter into Google to find who makes a library of controls that would include what I'm describing?
