Multiples links in primary menu

Hello, please your help…
I only can put one link in principal menu of Sidney theme
In Wordpress admin panel path --> Appeareance / Menus / Manage places
Page says:
“Your theme supports a single menu. Choose how you would like to use.”

But I see all examples have multiples menus…
Must I configure something to can make it?

Thanks a lot!

Hello there,

It only supports one menu location in the top header area. You can have as many as menu items placed in a single menu.

Here is how we did it.
