Creating specific front pages for departments The Drupal 7 site I am working on has its own company front page, and there are a couple of branches of the company in different location. I want to add specific front pages with "about / contact us / other menus" for each of those departments/branches of the company that will be displayed when each of the branches is accessed. 

How can I achieve this?
If you don't want to code, and you are familar with context module you can use this Context Reaction Menus.
Add new context with a URL as a condition, for example "department1/*" and as a reaction change the main menu, this will change in all pages that start with "deparmente1"
