A content management system including a document management system provides documents that include previews of folders in the content management system. The folder preview interface saved in the document is persistent despite changes to the folders stored by the content management system. In addition, previews of individual content items displayed within the folder preview interfaces are synchronized with the corresponding content items on the content management system. In some embodiments, the document may include other types of media including text, images, tables, video, etc. in addition to any embedded preview interfaces. Folder previews may also display previews of subfolders within the folder. A subfolder preview may display a list of content items within the subfolder. A user may also arrange multiple folder preview regions within the same document.
