To answer your question as best I can I would suggest you make use of the Language Pack (Preview) see below: I have gathered up some information which I believe might be of help, please feel free to ask any further questions regarding the information that has been provided. To understand what the Language pack does see: (1) http://help.k2.com/onlinehelp/K2Five/ICG/5.3/default.htm#Install/Manual/Simple-Language.htm Is it required to copy the runtime/design time folders for FBA K2 Apps? (2) http://help.k2.com/onlinehelp/K2Five/ICG/5.3/default.htm#Configure/Localize.htm Basically any SmartForm’s controls and certain properties, static labels are displayed in the selected language. If an application uses a SmartForm in some way the form will display in the selected language. See http://help.k2.com/onlinehelp/K2Five/ICG/5.3/default.htm#Install/Manual/Simple-Language.htm For specifics on installing the language pack, specifically the note stating “In a distributed environment the K2 Language Pack (Preview) needs to be installed on the K2 Application Server(s), the server(s) hosting the K2 smartforms design time site and the server(s) hosting the K2 smartforms Runtime site.” What is the impact on the K2 App for SharePoint? If you have the language pack installed and use any of the SmartForms like the Edit, Display forms together with any forms designed in the K2 for SharePoint App it will display in the selected language. Please Note: The language pack is in Preview mode and no active development is currently being done on it. The language selection is limited to the list of languages shown in the compatibility matrix There are known issues and limitations as described in the important considerations and Known issues section in http://help.k2.com/onlinehelp/K2Five/ICG/5.3/default.htm#Install/Manual/Simple-Language.htm. Thank you and kind regards, Dumisani

Hi Dumisani

Thanks for your reply.

But the language pack only depend on the browser language sort set, and only reflect to your designer or management, not the smartform you design.

I have designed a smart from in English language. 

I chose Japen language but my smart form's label didn't change to  Japen  language as below:

We need to translate K2 smartform label/watermark/dropdown values… to other language.

Please guide me how to implement it, Thanks~

Hi Kukutseng, 

Thanks for your feedback and I'm currently investigating further for a more concrete and robust solution, and will relay back to you once I have gathered the  relevant information regarding the correct procedure/process to follow, however in the mean-time during my research, I have a very interesting topic here on our community site which was based upon the same topic, please see the topic here as it contains good information especially the comments made by " @Prajwal_Shambhu" in the meantime whilst I continue to investigate further:
