Hi Samuel,
Thanks for reaching out.
In that case, it’s not currently possible. What was provided on that thread is a custom code, since there is no way to add logo to the off-canvas menu (as it’s for a menu only). But as @VGonzaloMartinez mentioned, it’s not working properly and will fail. Unfortunately, we don’t provide customization here in the forum, what’s been provided are just idea on how to implement it and it’s the user responsibility to maintain, which now doesn’t work.
But as said on other thread, it’s already added as feature request.
Thanks!
