I have a menu in my Twenty Eleven child theme that has some hierarchical items. Twenty Eleven handles it just fine, of course, but my client likes the fancy-looking menu animation that you can see on this site. I don't need the horizontal style that shows up under the "Resources by Topic" item, just the on-hover expansion like the "Who We Are" heading. I have used jQuery quite a bit before in other (non-WordPress) websites, but don't know where to begin in this case. Is this animation possible with Twenty Eleven?

The answer is yes. It is possible with some jquery. I think your question is still too broad. Also, asking for plugin recommendation is on the don't ask list. Id start doing some Google searches for implementing jquery in a wordpress menu, attempt and maybe ask for help with your code if it is not working. Otherwise a quick search for wordpress menu plugins will give you lots of addon choices.
