[TYPO3-commerce] Missing attributes in dropdown-list

[Robert Grede]

hi list,
after selecting a value in the attribute dropdown-list, the site goes
refreshed and the correct article is shown. But now the dropdown-list has
just only the selected value in it.

Example-Dropdown-list:

blue
green
red

After selecting blue:

blue

Is there any method to get the two other values in it?

Thanks,
Robert Grede
