Customize/Collapsible Archive Format

Does anyone know how to achieve the same sort of collapsible formatting available in Blogger? In blogger, I am used to being able to expand the year into months, and the months into individual posts. In WP, when I try to expand the months I am taken to the last post for the month, but there’s no expanded list of posts made during that month. I’ve been searching for two hours, and have only found one plug-in option in WordPress, which apparently isn’t compatible with 3.3.1.

Here’s what I was able to do in Blogger: http://pebblewriter.blogspot.com/

Thank you in advance.
