[TYPO3] jp_teaser and PIDinRootline

[Michael Tamburini]

Hello, I'm using jp_teaser extension to put in my pages the abstract
of other pages. I would like to set a different style for the title of
the included pages according to the "category" of the page.
"Categories" are the menu first level elements, so in regular page I
used

[PIDinRootline = x]
classTitle = titleXxxx
...[etc]...

where x is the PID of the first level menu element. How can I check
the PIDinRootline of the included page?

Thanks for your help,
bye!
