313367 Wordpress Posts Slide Open

Hello, I have started to design my own Wordpress theme, but there is one technical issue that I require assistance with. I need posts on my blog to be hidden by default when someone enters the page, with only their title showing. Clicking on a post's title will cause the content to slide out from under the title. Clicking again will cause the entry to close. I have mockups to show. I'd like to use Mootools and [login to view URL] to accomplish this, although I am open to other methods. I would like any modifications to the markup on my site to be heavily commented. Thank you. MK
