[TYPO3-commerce] Articles drop down list in product detail view

[Kevin Ulrich Moschallski]

Hi,

does somebody know how to set-up a article list as drop down menu in 
the product detail view like the one on 
http://www.kneipp.de/de/produkte_bestellung/baden_duschen/duschen/produkte/Gesundheitsdusche_Muskel_Aktiv_Wacholder.html 
?

Is this possible with TS or maybe in the template? Or does i have to 
implement it via an extension?

Thanks for help in advance.
