trying to hide/show some content dynamically

[Porcupine]

I'm wondering if there is a way to:

1. show a link on a page
2. click the link, and have content drop down (like a drop-down menu, only with about a paragraph of text and a photo)
3. click another link, have the first content go away and the new content drop down.

thanks for any pointers.
