{{Portal subpage| <subpagename> | [Boxfootertext] [|headertemplate=(Custom header template)]}}
for example: {{Portal subpage|November 2006}} {{Portal subpage| 1 | See more... |headertempate=Box-header/1}}
This will output a box made from the portal's /box-header page (or if that does not exist the default {{Box-header}} template), which contains a link to the subpage and below the content of the subpage.
