Hi there. Would you please consider the following feature request.
Currently you can assign only one menu to show in the header. Would it be possible to add another variable in the header options at the bottom of the page editor to select an alternate menu? That way if you had a site with several sections you could use multiple header menus.
If this isn’t something that you could do quickly what would it cost for me to sponsor this update? I really need it for a site i’m building at the moment.
I hope you are well today and thank you for your question.
This is actually a plugin territory and not theme.
You can try achieving this using any of the following plugins
Or you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
