Hello! Can someone help me with simple code? I made software and I want to add option that can change languages.

Example:

Dropdownmenu:
- English
- Serbian
- French
...

When I select English, my software changes to English
When I select Serbian, my software changes to Serbian
...

Thanks!

Yeah, that's not simple. Internationalization and localization are rather difficult, especially if you want to support widely variant languages like English and Arabic.

Give this resource a look through and see if it helps.
