In Elxis you can organize content either using an Hierarchical structure or Autonomous pages. A combination of these two ways is also possible. You can use both ways at the same time. In Hierarchical structure the content is organized in Sections -> Categories -> Content Items (articles). You can afterwards create menu items that link to any of these elements and specify how each page will be displayed (section table, category table, section blog etc). Autonomous pages are content items that do not belong to a Section/Category structure. They are independent. You can think of them as single HTML pages. You can create as many as you need and then organize through the proper menu structure.
