How to wrap template using ngForTemplate?

问题

I try to make ListView component using ngForTemplate for custom templates

list-view.component.html

<div class="list-view">
    <template ngFor [ngForOf]="items" [ngForTemplate]="template">
    </template>
</div>

list-view.component.ts

@Component({
    selector: 'm-list-view',
    styleUrls: ['./list-view.component.less'],
    templateUrl: './list-view.component.html'
})

export class ListViewComponent {
    @Input() items: any[] = [];

    @ContentChild(TemplateRef)
    template: any;
}

When I use it like this:

<m-list-view [items]="categories">
    <template let-item="$implicit">
        **some HTML markup**
    </template>
</m-list-view>

the resulting is:

<m-list-view>
    <div class="list-view">
        **some HTML markup**
        **some HTML markup**
        **some HTML markup**
        ...
    </div>
</m-list-view>

but I need this:

<m-list-view>
    <div class="list-view">
        <div class="list-view-item">**some HTML markup**</div>
        <div class="list-view-item">**some HTML markup**</div>
        <div class="list-view-item">**some HTML markup**</div>
        ...
    </div>
</m-list-view>

What should I do to wrap each list view item template in div.list-view-item?

回答1:

update Angular 5

ngOutletContext was renamed to ngTemplateOutletContext

It is now advised that you use the following syntax:

<div class="list-view">
  <div class="list-view-item" *ngFor="let item of items">
    <ng-container *ngTemplateOutlet="template; context: item">
    </ng-container>
  </div>
</div>

original

<div class="list-view">
  <div class="list-view-item" *ngFor="let item of items">
    <template [ngTemplateOutlet]="template" [ngOutletContext]="item"></template>
  </div>
</div>
