[TYPO3-commerce] TS for restricting countries in billing form

[hartmut]

Hi,

for those who want to restrict the country list in the billing form and 
don't know how:

plugin.tx_commerce_pi3.billing.sourceFields.country.select =
cn_iso_3 IN ('DEU','AUT','CHE')

(all in one line)

This example restricts the countries to Austria, Germany and Switzerland.

cheers
hartmut
