Hi, I have a KB for my app with one "Advanced Search" section. There I have 2 subsections (companies and People). How do I associate an article with the "Advances Search" main category? The tree is:

Advanced Search

| ---Article

| --- Companies (Subsection)

|         

|---- People (Subsection)

When I edit the article, there is no option for "none" in the subsection.

Is it possible?

Thank you.
