Dropdown Menu within a Page

Are there any good plugins that would allow placing a dropdown menu on a page, within the contact area? I’ve been searching but no dice.

This would be an example of the usage I’m trying to fit:

Click on Main Menu item -> Muffler Shop Locations

On the Muffler Shop Locations Page you are presented with no content, other than a dropdown menu.

The dropdown menu lets you select your Country – USA, Canada, Spain, Chile, etc…

Once you make your selection – the page populates with content below the dropdown menu. Dropdown remains in place in case you need to select another location.
