A folder in Cascade CMS is a container for related assets such as pages, references, and even other folders. Every folder needs an index page, which is required in order for the navigation menu to display properly on the site.
Navigate to the folder where the new folder will be created. To select the folder, hover over the desired folder and click on the > Arrow to the right of the folder name. Note: Every folder requires an index page. Cascade uses the index page to properly display the navigation menu in the site.
