Comment view
The Comment view web part needs to be placed on a blog post document. It allows users to post comments on the blog post and express their opinions on the topics and ideas contained in the blog post. The web part then displays a list of these comments using a specified transformation. A live example of this web part can be seen when viewing a blog post in the sample Andrew Jones Blog on this website.
The web part belongs to the Blogs module. Full documentation of the module can be found in Kentico CMS Developer's Guide -> Modules -> Blogs.
