Help showing posts in archives widget

Using the category and archives widgets in the sidebar. I'd like it to be so that the lists appear collapsed, on click they will expand to show the post titles. I've searched to forums--seems most people are having problems with collapsing.

It's probably some setting I'm missing, but I can't figure out how to get the post titles to show at all.

My archives look like this (no post titles at all):
Archives:
Dec 2010
Nov 2010
ETC

Here's how I'd like them archives and category widgets in the side bar to be expanded:
Dec 2010
-post title 1
-post title 2
Nov 2010
ETC

Appreciate the help
