Thank you for your answer.
I found the codes for breadcrumbs in header-extension.php file.
But I don’t perfectly understand it.
You mean this theme Interface-Pro already had this function and can be used in the position-linked menu without any installation Breadcrumb NavXT plug-in?
Or must be also installed NavXT plug-in besides ‘header-extension.php file function’?
If I don’t need to install NavXT plug-in, How can I control and get activate the function that’s in header-extension.php file?

Thank you.
