jQuery Collapsible Menu

** NOTE:
Try expanding each column one at a time. Then try expanding multiple columns. You will see that when a column is expanded that pushes past the page width, it wraps. I've tried a few things in the css (some styles are still in place) but with no success. This occurs in FF and IE.
This grid script that I've been working on is meant to be used in an online reports page and will be loading a much larger number of columns that I currently have displayed.
