bug: Toggle IonAccordion from Controller

Feature Request

Ionic version:

[ ] 4.x [ ] 5.x [X] 6.x

Describe the Feature Request

I would like to toggle a specific Accordion from my Controller.

Describe Preferred Solution

In Angular:

@ViewChild('accordion')
accordion: IonAccordion;

someMethode() {
    this.accordion.toggle();
}

Okay understood 😊

I don’t think that there would be extra programming for the user, as if we would use the same function like on the Accordion Click, the other Accordions would collapse (if not multiple) automatically?

In order to do this, ion-accordion would have to set the value of ion-accordion-group automatically which is a practice we moved away from with v5 because it caused a lot of synchronization issues (for example, we did this with radio: https://github.com/ionic-team/ionic-framework/blob/master/BREAKING.md#radio)

Glad setting the value property works. Also sorry I misspoke, accordion group does not have ngModel support since it’s not a form element.
