As I know there is no built-in property for this. You can work around by using Enum type and add xml translations for appropriated enum.
Here is the reference link https://world.episerver.com/blogs/russell-mercer/dates/2015/1/post-title/.
When displaying the choosen value then you should get translated value instead of real value
Thanks, that similar approach we already used at some blocks. However that requires some custom form elements to create this functionality within EPI Forms unfortunately.
You could submit this as a feature request in this forum: https://world.episerver.com/forum/developer-forum/Feature-requests/
you could give a try for db localization provider (that supports enum based properties) - https://blog.tech-fellow.net/2018/12/29/localized-episerver-enum-properties/
at least it translates values for specific languages for episerver admin ui, I'm a bit off the ring how it was implemented for forms tho... so just a speculations here.
Currently on a multi language site we want to use a Multiple or single choice field. However the items are not translatable in a different language. At least the choice how it is displayed in the front-end should be translatable as this might need to differ per language. Is this something that will be built-in in future releases?
