Okay. First, I think we need to clarify what navboxes are. Navboxes are a type of template. The purpose of navboxes is to help users navigate around the wiki; not warn users of spoilers. Spoiler warnings would be a different type of template.

You create a template like you would any other page. The difference is that they are in the template namespace. For example, instead of "SomeName", it would be called "Template:SomeName".
