Place menu anywhere on site

My theme supports 3 menus. I can place my menus in my header, on my portfolio page or my gallery page.

What I want to do is create a menu called online store and place it at a certain location on my online store template page.

How can i do this?
Is there a plugin that does this?

Can I create a menu and simply “call”(whatever the php term is) the name of that menu and place it on my online store template page?

Thanks
