[TYPO3-commerce] Marker for category_product

[michael.schneider at 3imsinn.de]

Hej,

I would like to add some new Marker into the template for the List and  
the Singleview. Further I would like to fill the Marker with a hook  
for pi1 'additionalMarker'. Have to say I tried but didn't get any  
result. Has Anybody a short example how to do this?

Thanks a lot
