How can I change the drop down menu to a a text menu on mobile.?

I found the section of code in the functions.php but don't know how to edit it.

Any help is much appreciated.

Hi!
Unfortunately, we don't provide any services for editing themes for individual users. If you don't like to use our responsive design you can simply disable it using the following instructions:
