[support] Limit a sidebar menu to appearing on certain pages

[Emma Badger]

I've created a custom content (business directory) that utilises the  
taxonomy menu and I've created a page called Business Directory which  
is in the primary menu.

I'd like the business directory taxonomy menu only to appear on the  
new business directory page and of course the pages that display the  
business directory entries.

Can someone point me in the right direction please?

Thanks.
