How to apply multiple template bindings on one element in angular

Question

I'm using template like following:

<ul [ngClass]="{dispN: !shwFilter,'list-group':true,'autoS':true,'dispB':shwFilter,'myshddw':true}" style=";display: none">
  <li *ngIf="itsNotF && itsNotF.length" [ngClass]="{bgDFF: !colps[j],'list-group-item':true}" *ngFor="let valm1 of itsNotF;let j=index;" (click)="togFltr(j)" style="padding: 0;background: #fff">
    <div *ngIf="valm1 && valm1.type=='1'">
      <h5 style="padding:8px;margin: 0;">{{valm1['header']}}</h5>
      <p style="margin: 8px;">{{valm1['body']}}</p>
      <h6 style="padding:8px;margin: 0;">{{valm1['note']}}</h6>
    </div>
    <div *ngIf="valm1 && valm1.type=='2'" (click)="modlTxt=valm1;notREadVu(j)" data-toggle="modal" data-target="#myModal">
      <h5 style="padding:8px;margin: 0;">{{valm1['header']}}</h5>
      <h6 style="padding:8px;margin: 0;">{{valm1['note']}}</h6>
    </div>
    <div *ngIf="valm1 && valm1.type=='3'">
      <h5 style="padding:8px;margin: 0;">{{valm1['header']}}</h5>
      <p style="margin: 8px;">{{valm1['body']}}</p>
      <h6 style="padding:8px;margin: 0;">{{valm1['note']}}</h6>
    </div>
  </li>
  <li [ngClass]="{bgDFF: !colps[j],'list-group-item':true,'lgOt':true}" (click)="logout()">
    <span class="title">Log Out <i class="fa fa-sign-out"></i></span>
  </li>
</ul>

So it gives following error:

EXCEPTION: Template parse errors:
Can't have multiple template bindings on one element. Use only one attribute named 'template' or prefixed with * ("one">
  <li *ngIf="itsNotF && itsNotF.length" [ngClass]="{bgDFF: !colps[j],'list-group-item':true}" [ERROR ->]*ngFor="let valm1 of itsNotF;let j=index;" (click)="togFltr(j)" style="padding: 0;background: #fff">
"): App@78:94

Previously it was not giving error I faced this issue after upgrading to RC4.

So what's workaround, so I can apply multiple template binding on single element without altering Template structure.

Can't use two template binding on one element in Angular 2 (like *ngIf and *ngFor). But you can achieve the same by wrapping the element with a span or any other element. It is good to append with an <ng-container> as it is a logical container and it will not get append to the DOM. For example,

<ng-container *ngIf="condition">
    <li *ngFor="let item of items">
        {{item}}
    </li>
</ng-container>
