[Type:] Layer [Important:] Make sure that you are very aware of the functionality in different browsers and that javascript needs to be activated to make this work properly. [Example:] 
Layer structure is interesting, the principle is to hide information until the visitor asks for it. Used correctly, this can be used somewhat similar to a Paralel structure. this way the user regains control over what information he wants/needs at any particular point. Take a web-shop as an example; you present a list of products to the visitor, instead of showing all the information around each product all the time, you show only the basic things, name, price, in stock. The rest are small links “Description”, “product info”, “pictures” and so on. Each of these links opens a layer that the visitor can choose if he wants. Done correctly, you don’t have to reload the window in the middle of a buying-process, you don’t spawn extra windows, just show and hide the info.
