Hi, I’m new to this forum and had the same question, so I wanted to share what I found based on the helpful discussion with the developer.

As mentioned by the developer:

Setting [animation]=”‘none'” only disables the open/close animation of the content. The ripple effect is a separate visual effect and isn’t controlled by the animation property.

To remove the ripple effect in Smart Accordion, you can simply add this CSS to your styles:

.smart-ripple {
display: none !important;
}
This completely hides the ripple effect when clicking an accordion item.

It worked perfectly for me — I think it will work for you too!
