With your content page open, select "WebAlliance Snippets" from the Snippet Drop-Down Menu.  Drag one of the Site Navigation Snippets on to your page where you want it to appear.

The Sub Item Navigation List snippet will add a list of links pointing to the children of the current page.  In this case, we are adding the snippet to the "History" page.  In the Site Navigation tool, "History" has been assigned sub items of "Company History" and "Where We're Headed". Because of that, "Company History" and "Where We're Headed" appear in the "Sub Item Navigation List" snippet on the "History" page.

The Sub Navigation List Snippet will show the entire navigation tree of sub items that are beneath the current page in the Site Navigation tool.  The above example shows "Company History" and "Where We're Headed" which are sub items of History, and also shows all other visible sub items that are assigned under "Company History" and "Where We're Headed".

The Sibling Navigation List Snippet will add a list of links pointing to "siblings" (at the same level in the Site Navigation) of the current page.  Using "History" as an example, the siblings are "Email Us", "Our Locations" and "About Us". In the Site Navigation tool, those pages would all be at the same level - under a parent item called "Contact Us".  The Sibling Navigation List Snippet will include a link to the current page as well - "History" in this case.
