Thanks for the issue! Could you share a bit more about what you're trying to pass here?

The collapsed indicator is a native button that can be styled using shadow parts:

ion-breadcrumb::part(collapsed-indicator) {
  background: pink;
  color: hotpink;
  border-radius: 8px;
}

Are you looking to override its styles, icon, or pass text? I just want to make sure I fully understand your feature request. Thanks!

@brandyscarney i know that i can adjust the style by using shadow parts, i want to change the collapsed indicator icon, or even better would be to be able to replace the whole button
