[TYPO3-shop] Dynamical refresh on 2.7.1

[Christian Lerrahn (Cerebrum)]

Hi,
on http://www.ttproducts.de/tt_products_ext.html it is mentioned that
tt_products 2.7.x can do a dynamical refresh when using variants.
However, I cannot figure out how to configure that. Does it require
markers in the template I haven't found, yet? Or is this a TS
configuration thing?

Cheers,
Christian
