Expandable Recent Comments Widget for Blogger/Blogspot

The Expandable Recent Comments widget for Blogger is a very accessible widget that can be collapsed or expanded through user interaction, so we don't have to click the author's name or post title link in order to read the content of a comment. The expanding content can be shown or hidden by clicking the plus/minus icon or by hitting the "Show all" or "Hide all" button.

To add the Expandable Recent Comments widget for Blogger, please follow the next steps below:
