I am wondering if it's possible to create a left sidebar or right sidebar that can show my sticky "table of contents" widget for each specific post?
this is possible of course, but you need to implement this feature individually. I strongly recommend using a child theme for direct code adjustments. A prepared child theme folder is linked in the Moka documentation.
Please understand that we cannot provide support for individual customizations.
Okay, no problem. Thank you for the response.
