Hello There,

Thanks for writing in! Regretfully there isn’t a feature in the builder that you can have the sub menu in a horizontal display. I would recommend that you use UberMenu plugin to have that kind of setup. To know more about UberMenu, please check this out: https://theme.co/apex/forum/t/extension-ubermenu/75

Hope this helps.
