Drop Down Submenu Creation

Hi,

I’m new to WordPress and took some time to set up submenus within my new website design which would drop down from the page top when selected, and allow access to deeper levels of the site.

However, now that I’ve installed the Onetone theme, those drop down submenus have disappeared and Onetone seems to insist on everything being accessed from a top level menu only. Is there any way to reinstate drop down submenus? I couldn’t find anywhere the page source which contained the menu controls could be edited, and I’m not sure how “friendly” Onetone will be with other plugins designed to provide drop-down features.

Could you please tell me if there’s an answer to this, or am I doomed to remove Onetone completely and find an alternative?

Being a bit of a newcomer to the WordPress / Onetone way of doing things, if you could be kind to me in your response and provide some extra detail so I don’t get lost, it would be very much appreciated.

Many thanks,

Marc
