Journal offers full multi-language support for text and images, however languages are not part of the theme, they are part of the core Opencart system and installed separately.
Journal will detect any additional languages installed on your system and will provide extra input fields for translatable text.
FREE or paid Opencart language packs can be found here: Opencart Extensions
After you find a suitable language pack, follow these instructions to install it on your store: Opencart Language Documentation
RTL and Arabic
Full RTL and Arabic support is built in Journal 3 store front. The theme will adapt automatically to RTL direction upon detection of RTL language activation.
RTL is not supported in the Journal 3 admin, only in the store front.
Journal Language Options
Language styling options are in the Language/Currency style found in Journal > Styles > Language/Currency.
The styles are applied in the header modules in Journal > Header > Active Header > Language/Currency.
