Hi Dejan Caric,

How can i call contentTypes_en.xml and contentTypes_zh.xml by culture wise , say when i hit the URL www.xyz.com/en-gb then contentTypes_en.xml will be called and when i hit the URL www.xyz.com/ch-zh then contentTypes_zh.xml  will be called?

Thanks !

contentTypes_en.xml and contentTypes_zh.xml will localize properties in edit mode based on the personal language you selected under My Settings section.

If you selected Chinese as a personal language, but you're editing a page in the English branch, property names will be displayed in Chinese.
