Hi

Thanks for the suggestion and for sharing the mockups.

At the moment, SP Page Builder’s Accordion addon doesn’t provide a dedicated CSS Class field per accordion item/title button—only the addon-level styling options are available. Adding a per-item CSS class option would definitely improve flexibility, especially for customizing individual accordion buttons.

We’ve noted your request and will add it in the Feature Request section. so it can be properly tracked and reviewed by our product/DEV team for possible inclusion in a future update.

Thanks again for the helpful idea and clear examples.

-Regards.
