Expanding and collapsing info with the (+) or (-) signs? help!

Hello-

I have been trying to do this specific functionality with no luck. I have a bunch of headlines that have (+) signs next to them. When the (+) is clicked, It expands a bit of text below it, changing the (+) to a (-). Clicking the (-) collapses the headline. This is something I have seen before, but am having trouble doing myself. If someone could point me towards a tutorial or a bit of code to clue me in, Id appreciate it greatly. Thanks!

-Eric
