Hey Deanna,
Thanks for reaching out to us!
How are the events currently being added to your homepage? Can you control the number of events that show up there?
Adding the ability to scroll can be handled pretty easily with a couple of CSS changes. To do that, you’ll just need to target the wrapper that contains the events in CSS and add a set height and “overflow: scroll-y” to that element. If you provide me with a link to your site, I can give you a set snippet that you can add to your child theme’s stylesheet.
Thanks!
