I have just started working with a website on glowhost and I am trying to set up sub pages under a main page. I want to then link a pdf to each subpage for easy access. How can I do this easily and quickly.

For example:

On the left hand side would be my main pages like
Home page
Ag page
Junior page

Then under ag page I want a link to other pages.

ag page
recipe contest
activity sheet
Book log

and when someone clicks on one of these sub pages, they will then link to a pdf or word document that they can print.

How can I do this. Thanks.
