The expandable synopsis is a new feature that allows you to display a brief description of the film, along with a longer synopsis.
With this feature enabled users will only see the short description, and awards. Once the “See more” option is selected, the description will expand out to reveal the synopsis, cast & crew, language, subtitles, country, and crew.
It is important that both the short description and synopsis fields are populated in admin. If one is not populated, the description will be blank when that part of the field is displayed.
