Wiki structure - pages and categories
Wikis don't use a separate category system. The entire structure is built from pages nested within pages, where top-level pages serve as categories and their children serve as articles. The result is a flexible tree that can be rearranged at any time without breaking links or losing content.
Page nesting
Any page can contain child pages, and child pages can contain their own children. A wiki might have a top-level "Getting Started" page with sub-pages for "Creating Your Workspace", "Inviting Your Team", and "Setting Up Your First Project". Each sub-page can nest further, so "Setting Up Your First Project" might contain "Task Boards", "Timesheets", and "Client Access" beneath it. Pages can be nested up to 5 levels deep, which covers most documentation structures without creating overly complex hierarchies.
Reordering pages
Pages are reordered by dragging them in the navigation panel. A page can be moved up, down, or nested under a different parent page, which changes the hierarchy instantly. The navigation panel updates to reflect the new order, so reorganising a wiki's structure doesn't require any additional steps beyond the drag.
Thinking in pages, not categories
There's no distinction between a "category" and an "article" in the wiki. Every item is a page. A top-level page can hold its own content and also contain child pages beneath it, so a page titled "Invoicing" can explain invoicing as a concept while also housing sub-pages that cover specific topics like payment methods, recurring invoices, and overdue reminders. The structure adapts to whatever suits your documentation needs.
