Regarding Language issues

My question is, I made application which work for different - different language like french, usa,Portuguese and many more, but problem is that in the last after performing all operation I want to store data in English only like,
example.
i have text box, inside that I mention --Please Select --, and by help of changeLocle Method I converted in french, but in back end i’m doing some query, with --Please Select-- , now problem is i’m getting error because already i changed --please Select – in french,
if you have any solution then please provide,
thanks

I don’t think that Webix have any tooling for such use-case.

By the way, you can use placeholders for text inputs. In such case empty input must have any text, but still will have an empty string value ( so you will be able to show “Please select” message in any language and have the single empty value )
