The announcement banner type supports up to five messages. Each message will be displayed for the number of seconds specified in the Display timer length setting. After the last message is displayed, the messages will start back at the beginning and loop indefinitely.
To display multiple announcements in a banner:
Select Announcement from the Active banner types
Set up the first message
Click the Add message button at the bottom of the first message
Edit the length of time each message will be displayed in the Display timer length section
Preview the banner at the top of the page. Use the preview dropdown to view the looping banner or a specific message.
Warning: You can only have one banner type live on your storefront at a time, but the Announcement banner type allows you to cycle through multiple messages.
