The above mentioned Category Sidebar component does what it promises: it presents the content of a specific page in the sidebar of a defined category. That’s useful.
Another thing is to have a menu sidebar where (selected) categories can be made into a sidebar menu to help navigation. That’s what they have done at Resonate, as @Hakanto explains here. One part of it is the Category Sidebar Widget, developed by Pavilion (they have contracted with them in the past to help them set up/customise their Discourse forum.
Sidebar
The sidebar we use is made by Pavilion. It’s called
Category List Widget - Layouts - Pavilion . Since we use our forum as a workspace, this is very helpful. Highly recommended
Apparently this isn’t an official Discourse forum, unfortunately, but if it is a valuable tool, we can install it manually.
