https://documentation.jomsocial.com/wiki/Translate_Toolbar - have you read what is written in this manual? it says there is no need to create more menu items for JomSocial Toolbar. There is a completely different way of translating the menu into different languages.
I didn't fully understand what you meant.
I have not finished making a multilingual site yet, but do I need to change something in the JomSocial menu now?
