Show text when clicking on button

Hi Folks,

I have the following website: http://beta.visueel-adv.be/nl. As you can see, there are a couple of news items. In fact, there should be 3 items on the homepage, the rest should be hidden.

When you click the button "oudere nieuwsberichten" what means "older news", the other newsitems should be shown underneath the 3 existing ones.

Is there a jquery plug-in to do so? Thanks a lot for your answer(s)!
