Can I define multilingual custom objects using Application Composer?

Use this topic to know how you can define multilingual custom objects in Application Composer.

Yes. You can first define a custom object using the base language English and then change the translations on the UI.

If you've a drop-down list, its values are translated in Application Composer through Functional Setup Manager > Manage Standard Lookups. If a contact lookup is a person's name, it will be displayed as is regardless of whether your sign in language is English or Japanese.
