Trouble setting custom attribute tags in Ionic 4

Trying to apply custom attributes within a ngFor loop is proving challenging for me.

<ng-container *ngFor="let a of this.current_items?.areas; let i = index">
  ...

I've made several attempts:

<div class="productBatchArea" custom-data='{{ a.title }}'>
// ERROR: Cannot bind to 'custom-data' as it is not a recognized property of 'div'

<div class="productBatchArea" [data-teste]="a.title">
// ERROR: Cannot bind to 'data-teste' as it is not a recognized property of 'div'

<div class="productBatchArea" data-teste="{{ a.title }}">
// ERROR:  Cannot bind to 'teste' as it is not a recognized property of 'div'

Is there something I'm missing in my approach?

Answer №1

Attempt it in this way

[attr.custom-data]="a.title"

Inform me if it does not function
