Hello,
You have probably found a solution but I just have the same problem and here is my solution using CSS.
In my case I had two languages. Given that each one have the class “lang-item” by default,
I selected the first one and add my separator after like this :
.lang-item::nth-child(1):after{
content: ‘ /’;
}
I hope it will help other people who have the same problem !
