Hi,
It’s the same with other templates in Joomla for the multilingual site:
1- Duplicate template style:
You can go to admin panel > Extensions > Templates > uber – [App] Home template style > duplicate this and rename + assign to homepage of other language on your site.
Also need to check the ‘Navigation’ tab and set the associated menu of that language for this template style so it can load correct menu for each language.
2- Duplicate modules:
The ‘ uber – [App] Home’ template style is assigned to ‘Homepage’, almost modules are assigned to ‘app-home’ position, you can do the same with template style, simply duplicate each module for each language and do the menu assignment.
Regards
