Answer 1

Sie brauchen so etwas wie zu tun:

<div *ngFor="let item of items"> 
    // you can access your item here for example 
    <h1>item.id</h1> 
    // and you can loop again 
    <div *ngFor="let temp of item.custom_attributes"> 
    <p> temp.attribute_code</p> 
    </div> 
</div> 

können Sie * ngFor verwenden

ein Array von Objekten iterieren

Answer 2

In Ihrem component.js,

private myItems:any = []; 

constructor(){ 
} 

yourFunction(){ 
    let vm = this; 
    items.forEach(function(val: any){ 
    val.custom_attributes.forEach(function(myAttrs: any){ 
     vm.myItems.push({ 
     "code": myAttrs.attribute_code, 
     "description": myAttrs.value 
     }); 
    }); 
    }); 
} 

in Ihrem HTML-Datei

<div *ngFor="let myItem of myItems"> 
    <p> Code: {{myItem.code}} </p> 
    <p> Description : {{myItem.description}} 
</div>
