Make it more like a wikipedia navigation page. I.e. keep it at the bottom of the page. Make it all collapsed by default.
Note: If there is nothing in the category (say for elementary and reading, then it will not show in the table. This is a good thing (because if we want to show it, we can change what the dpl returns for no results (ie, we could have it return "No lessons yet" or whatever). For now i will leave it as nothing as it looks better than saying we have nothing.
