[TYPO3] Parent Id of the root page.

[universe]

Hi,

I want to retrieve my parent ID of the root page level in typo script. The 
option  page:pid only retrieves the parent page id. If I have a tree 
structure of 5 branches it will not work.



The goal is to have a different template on all the trees.

An other option is to write multiple templates but that is hard to handle.



Anyone an idea??

Regards,

Tom
