Issue with Angular Checkbox: Inconsistencies in reflection of changes

I'm encountering a challenge with my Angular application where I have implemented multiple checkboxes within an options form. The issue arises when changes made to the checkboxes are not consistently displayed as expected. Below is the pertinent code snippet:

<form class="theme-form">
    <div *ngFor="let contactType of contactTypeDataList" class="checkbox-theme">
        <label [for]="contactType.Type" class="arrow-labe2">
            <input class="form-control" [id]="contactType.TypeId" class="styled" type="checkbox"
                [checked]="contactType.IsActive"
                [value]="contactType.TypeId" (change)="onTypeCheckboxChange($event, contactType)">
            {{ contactType.Type }}
        </label>
    </div>
</form>

Answer №1

It seems like you are statically setting the [id] attribute as empty when it should be dynamically set using [attr.id]

<form class="theme-form">
    <div *ngFor="let contactType of contactTypeDataList" class="checkbox-theme">
        <label for="contactType.Type" class="arrow-labe2">
            <input class="form-control styled" [attr.id]="contactType.TypeId"  type="checkbox"
                [checked]="contactType.IsActive"
                [value]="contactType.TypeId" (change)="onTypeCheckboxChange($event, contactType)">
            {{ contactType.Type }}
        </label>
    </div>
</form>
