ionic 4: <ion-reorder> not working as expected

Question

i'm working with ionic 4 angular 7. I'm using <ion-reorder> to reorder list. Drag n Drop works for the first time fine but when I release the click, item got stuck. After first reorder everything freezes. And I'm unable to attempt reorder for the second time.

Here my .html file

<ion-list lines="none">
      <ion-reorder-group disabled="false">
        <ion-reorder>
          <ion-item>
            <ion-thumbnail no-margin item-start>
              <img src="../assets/images/5.jpg">
            </ion-thumbnail>
            <div class="pl-2">
              <h5 no-margin>Multan</h5>
              <p no-margin>Historical place...</p>
            </div>
            <ion-buttons slot="end">
              <ion-button>
                <ion-icon slot="icon-only" name="close"></ion-icon>
              </ion-button>
            </ion-buttons>
          </ion-item>
        </ion-reorder>
        <ion-reorder>
          <ion-item>
            <ion-thumbnail no-margin item-start>
              <img src="../assets/images/5.jpg">
            </ion-thumbnail>
            <div class="pl-2">
              <h5 no-margin>Multan</h5>
              <p no-margin>Historical place...</p>
            </div>
            <ion-buttons slot="end">
              <ion-button>
                <ion-icon slot="icon-only" name="close"></ion-icon>
              </ion-button>
            </ion-buttons>
          </ion-item>
        </ion-reorder>
        <ion-reorder>
          <ion-item>
            <ion-thumbnail no-margin item-start>
              <img src="../assets/images/5.jpg">
            </ion-thumbnail>
            <div class="pl-2">
              <h5 no-margin>Multan</h5>
              <p no-margin>Historical place...</p>
            </div>
            <ion-buttons slot="end">
              <ion-button>
                <ion-icon slot="icon-only" name="close"></ion-icon>
              </ion-button>
            </ion-buttons>
          </ion-item>
        </ion-reorder>
        <ion-reorder>
          <ion-item>
            <ion-thumbnail no-margin item-start>
              <img src="../assets/images/5.jpg">
            </ion-thumbnail>
            <div class="pl-2">
              <h5 no-margin>Multan</h5>
              <p no-margin>Historical place...</p>
            </div>
            <ion-buttons slot="end">
              <ion-button>
                <ion-icon slot="icon-only" name="close"></ion-icon>
              </ion-button>
            </ion-buttons>
          </ion-item>
        </ion-reorder>
      </ion-reorder-group>
    </ion-list>

When I drag n Drop Item. It get stuck when I drop it. After this, everything freezes.

Any Help...?

I'm using

Ionic: 4.10.2 Angular: 7.3.0

I think you need to store your data in a variable and ngFor on these data to build your reorder items.

this.items: Array<img: string; title: string; description: string; icon: 
string> = [yourArrayOfObjects];

I think then you need to catch the ionItemReorder event like this

<ion-reorder-group (ionItemReorder)="reorderItems($event)" disabled="false">

and in your .ts the reorderItems() function could be

reorderItems(ev) {
    const itemMove = this.items.splice(ev.detail.from, 1)[0];
    this.items.splice(ev.detail.to, 0, itemMove);
    ev.detail.complete();
}
