Seperate menu with a line

Hi there,

Try adding a custom class separator to the menu item you want to add the separator on the right:

Then add this CSS:

@media (min-width: 769px) {
    .main-navigation .main-nav ul li.separator a {
        border-right: 1px solid #fff;
    }
}

Adding CSS: https://docs.generatepress.com/article/adding-css/

Let me know if this helps :)
