Hide Hyperlink Destination on the Same Page?

Hello all! Please take a look at this website first: Senseware Exhibition

Notice when you click hyperlinks (highly thermoplastic non woven fabric, 3D spring structures, stretch fabric, triaxial woven fabric, etc.), the slideshow layout remains the same, but only images and contents on the bottom change?

I want to achieve the same effect on the wordpress page and I think it has to do with hiding all hyperlink destinations(contents) on the same page except the one we are seeing? The way I did was, one, create a page template, two, insert the php ‘portfolio slideshow’ and write down contents when I create a new page, three, try coding on the page template so that every slideshow and contents except the active one will be hidden.

Since I know little of php coding and javascript, I am having a difficult times with it. Am I doing completely wrong? I am making this wordpress website so that my friends who have no idea of writing code can write/upload. Could anyone tell me what I should do make the same effect as the link above?

Thank you so much in advance.
