Dropdown Menu In Sidebar...

[BWalt302]

My website has a javascript drop down in the left sidebar for navigation. It includes Categories, and when you highlight one, Sub Categories Pop-out. The issue is Google for some reason is reading this as content, and it is effecting out SEO. What can be done to prevent this from happening but still have the individual pages be index and content read?

The only solution that comes to my mind is to use an IFrame for the navigation. The IFrame should then load its file from a directory that is blocked by robots.txt.
