Wordpress filter + page question

Hi Guys,

Bear with me cause I'm bad at explaining.

I'm looking to code a filter system where it shows a different page with ajax.

x = pageOne
y = pageTwo
z = pageThree

On the product page (custom made) I want the buyer to click on x,y or z and be shown that page without having to navigate off the page.

Are there any plugins for this or do I have to fully custom code it?

I hope that you have found already your solution, but for any case here is a link to a tutorial for your question:

I actually fixed it with the 'Insert Pages' plugin

Works great.
