I am developing a site using SXA components and the site requires an indication section above the header. The indication pertains a few lines of text, read more, and close buttons. Only a few lines of text are shown when a user comes to the page. After the user clicks "read more", the remaining lines of text appears. I'm not sure which component would be best to use in this situation and was wondering what would be the best way to achieve this? The site is calling for an ISI tray to appear at the bottom of each page that will function very similar to the indications tray above the header.
