My documents are organised this way

Product 1 support center
Product 1 Internet user guide
Chapter 1
Page 1
Page 2
Chapter 2
page 1
...
Product 1 DVD user guide
...

When I access the Product 1 Internet user guide from the support center page, i need to display only the Internet user guide table of content.
I tried to achieve this via the tree menu but it shows all documents, in this case it shows also the DVD user guide.

Does someone have any idea on how to get to that?

Thanks in advance.
