[TYPO3] Template infi in Constants depending on record id

[mohamed boujataoui]

hello,

how can I define that 2 "loginbox" (using newloginbox + 
newsloginbox_templte) on the same screen have different layouts. In this 
  certain case I have an "standard" loginbox in the header on every page 
but on some pages I want to have additional loginboxes in the content 
area with an other layout. I think that the template information must be 
  made record (tt_content id) dependent. but how?
I didn't find so far any hints in docus or mailing lists.

regards,
