Hi @tperry ,
Do you want to transfer the items in the drop down?
Could you show me the formula that you use to transfer the items in the drop down?
If you want to transfer all the language in the app, you could choose language in powerapps studio.
Then all the words in powerapps will change automatically.

If you want to transfer inside the app, you could consider using MicrosoftTranslator connector.
Try this formula: (set the drop down's Items)
Split(MicrosoftTranslator.Translate(Concat(listname, fieldname & ", " ),language that you want),",")
Best regards,
