Hidden Sidebar

Hello ??

Unfortunately not from the panel.

Both these modifications require code edits.
We do such only for Rife Pro users with active support.

So I will not be able to help you here, sorry.

If you plan to do these edits in header templates and function I would advise using child theme https://rifetheme.com/help/docs/installation-updating/installing-the-rife-child-theme/

With kind regards.
Air.
