We published a new tiny plugin that triggers animations on the items of your Repeating Group within your page when they enter/leave the viewport.
You can choose different animations, delay, duration, and easing so you can control the user experience as your needs.
Simply place the plugin on the page, and it should work for old and new responsive systems.
Plugin: Repeating Group Animation On Scroll Plugin | Bubble
Editor: Plugin-protos | Bubble Editor
Demo Video: Loom | Free Screen & Video Recording Software
Any feedback would be appreciated.
