Default install of Sage theme failed to display the Primary Menu

Hi there,
I have just started with the Sage and Bootstrap, by following the tutorial, link given as below

but the default installation failed to load the menu as being demonstrated in the video itself. Been to the discourse and now I know it’s because the Bootstrap Menu has been taken away and it can be restored by using the ‘wp_bootstrap_navwalker’ and in fact restored it as well.

As this is something I have been forced to do so would like to know how can we make it work out NavWalker Class?

I am sure there are several other people interested in this topic as well :slight_smile:

Thanks for your response, been to this post BUT want to make it happen without BootStrap and/or wp_bootstrap_navwalker class.
