Hi!

I need a very simple CMS, with these characteristics:

-Navigation tree (max 3 levels)
-Manage single and multiple pages (like "product" page that can be
repeated N times for N products)
-For every page, choose a template. The template indicates the content
to provide (title, text, 2 images, 1 pdf...)

Is there any CMS that is suited for me (eventually with some
customization). Drupal?. Or is it better to start programming from
zero?

Thanks, Bye Max!
