The Read More snippet allows content authors to hide large amounts of content that might not be relevant to all users. Many news sites use this technique to show the first few lines of a news story and then hide the rest.
This snippet is available to everyone today in the snippets list. Place the content that you want to be hidden in the snippet similar to how a panel snippet works.
Content that is placed here will show the first 100px (about three text lines) and fade into the background color. A read more link will be placed at the top that allows the user to continue reading the content.
