How can I create an Accordion List within ionic 2?

Question

I want to integrate an accordion in my project using expandable groups but for a recent project, I was needing a rendition of an accordion that expanded text or more precisely overflowed content.

Can you tell me how it will done within ionic 2 ?

Check the demo of accordion list within ionic 2 on Github :

<ion-content padding>
  <ion-list>
    <ion-list-header>
      Ionic 2 Accordion Example.
    </ion-list-header>
    <ion-item padding *ngFor="let d of data" (click)="toggleDetails(d)"><ion-icon color="primary" item-right [name]="d.icon"></ion-icon>
      {{d.title}}
      <div *ngIf="d.showDetails">{{d.details}}</div>
    </ion-item>
  </ion-list>
</ion-content>

.ts

export class HomePage {

  data: Array<{title: string, details: string, icon: string, showDetails: boolean}> = [];

  constructor(public navCtrl: NavController) {
    for(let i = 0; i < 10; i++ ){
      this.data.push({
          title: 'Title '+i,
          details: 'Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

          icon: 'ios-add-circle-outline',
          showDetails: false
        });
    }
  }

  toggleDetails(data) {
    if (data.showDetails) {
        data.showDetails = false;
        data.icon = 'ios-add-circle-outline';
    } else {
        data.showDetails = true;
        data.icon = 'ios-remove-circle-outline';
    }
  }
