I am planning to build a knowledgebase for my company. This is all currently done in MS Word, and stored in document libraries.
I'm exploring whether a Wiki pages library is the way to go for this.
I've seen examples where there is a navigation tree on the left hand side of the page, completely customized, with collapsible titles, subsections, etcetera. A bit like the table of contents you can generate in a Word document.
How is this done? My company still uses classic Sharepoint, but will be migrating to Sharepoint Online soon.
Is this only possible in Sharepoint Online? If yes, how?
