Override Header, add Side Nav

Hello,

My org uses Enfold pretty much as a default for WP sites. I’m currently on a project where the client wants a side nav. I’ve searched through the support a bit for some ideas but they’re all coming up short in some way or another. Basically, I’m looking for the best way to disable the header/menu and create a left-side vertical nav area — responsive similar to the main header nav menu.

I’ve tried implementing Sidr without much success, and I’ve tried the various suggestions to just set display:none on the header (Might’ve been an update since that support question as the targeted class in that answer does not exist. I tried it on the main header’s id, but the body still maintains the offset in a data attrib.)

Just wanted to see if there was a friendlier way to accomplish what I’m trying before I go digging deeper. Thanks.
