How to completely remove responsive menu?

I’ve been searching the last 3 hrs trying to remove the mobile menu from my site with no luck. Any help is greatly appreciated.

evolve child theme

I was able to remove the mobile menu icon using style css:

<blockquote>#wrapper .dd-container .dd-selected-text {
  display: none;
}

But that simply hides the button and the mobile menu functionality remains. Bit weird. The button is gone but clicking that area still displays the menu.

I’ve added a plugin to handle the mobile menu and would just like to remove the standard menu included in the evolve theme.

Thanks for any help.
