Did you read the documentation? There’s a parameter you can use in the shortcode to show the content from your posts:
content – WARNING: If you want to show the content on your listed posts, you might want to do this from a new Page Template or a Custom Post Type template. Using this parameter is discouraged, you can have memory issues as well as infinite loop situations when you’re displaying a post that’s using List Category Posts. You have been warned. Usage:
yes – Show the excerpt or full content of the post. If there’s a <!–more–> tag in the post, then it will behave just as WordPress does: only show the content previous to the more tag. Default is ‘no’. Ex: [catlist content=yes]
full – Show the full content of the post regardless of whether there is a <!–more–> tag in the post. Ex: [catlist content=full]
