I want to display a part of the article in the "Read more" part.
You can edit it by "Continuation of article" on the "article management> new posting" screen on the blog management screen. Since there is a space for entering "Continuation of article" to be opened and closed by clicking under the article body area, please write in the article there and press the "Post article" button and display it in the "Read more" part I can.
For details, please refer to Usage Manual> Blog> Article Management> Continuation of Articles.
