Navboxing

I want to make a navbox for achievements, but my first version doesn't look great.

As you can see, the template can't handle such a large group. Not very surprising, as the main game has fifty achievements. I've been trying to think of subgroups, but I can't figure out what it should be. Does anyone have ideas? Also, are there other navboxes or templates you would like to see?

Edit 1: Subgroups do solve the problem, as demonstrated here.
