There should be an accordion there (using the WP UI Plugin) starting with Medical Devices and going down through Automotive. This stopped displaying about 6 weeks ago, even though it was displaying fine up to that time. When I look at the page using Firebug, I can see that the problem is that none of the CSS is being applied as specified in the code. I have updated the WP UI plugin to the latest version (0.8.8) without any effect on the missing accordion (updated from the previous version 0.8.5 where it was working well and then vanished).
