Hello,
Thank you for your question regarding nested sub-menus. I’m glad these worked in your initial development. I regret to hear that they no longer showed up after the site was viewed in “real time”. I understand the term real time, but I’m not sure what it means in this context. Do you mean that you when you moved the site from the staging environment to the active environment that the menus did not appear as they had been set before?
Best,
Christopher M.
