Hello,
Vehicle manager free and pro support multi language site.
But if for Pro version all languages go included in install package. In free version - you need self add language files:
Please check ours documentation page:
ordasoft.com/Vehicle-Manager/vehiclemana...ture-comparison.html
In free version you can't create menu to alone category built in Vehicle manager tools.
In Free version Vehicle manager, link to category you need build as "external link" type.
So you go to catgory link to what you need create as menu, save that link, next you go to jomla menu manager - and create "external link menu item" and sate for it link what you saved before and set language - what you wish
Thanks,
OrdaSoft team
