adding menu to directory listing

Hello!

Looking for some direction here on how to add a “menu” to a directory listing. I want my customers to have the ability to create a menu so when people view the directory listing they can also view the customers menu. Ideally this would show up as a field which can be edited and updated by the customer. Can you show me where the documentation is to do this?

Thanks for the help! Let me know if you need clarification on my request
