[TYPO3-english] tt_content element on every subpage

[Sergio Catalá Gil]

Hi list, 

I would like to have a banner (tt_content element) on left column on
EVERY subpage of a root page and editors would have the possibility to
edit this banner ALWAYS. How could this content to be added
automatically to every subpage on left column without the need to create
it on every subpage?

My template looks like this:

temp.MainTemplate {
  ....	
  subparts.FLASH < temp.Flash
  ....
  subparts.BANNERS_LEFT < styles.content.getLeft
  subparts.BANNERS_LEFT.stdWrap >
  subparts.BANNERS_LEFT.renderObj.stdWrap.wrap = <div
align="left">|</div>
  ....
}


Thanks in advance, 
Sergio
