[Fixed] How to use *ngIf else?

Issue

I’m using Angular and I want to use *ngIf else (available since version 4) in this example:

<div *ngIf="isValid">
  content here ...
</div>

<div *ngIf="!isValid">
 other content here...
</div>

How can I acheive the same behavior with ngIf else ?

Solution

Angular 4 and 5:

using else :

<div *ngIf="isValid;else other_content">
    content here ...
</div>

<ng-template #other_content>other content here...</ng-template>

you can also use then else :

<div *ngIf="isValid;then content else other_content">here is ignored</div>    
<ng-template #content>content here...</ng-template>
<ng-template #other_content>other content here...</ng-template>

or then alone :

<div *ngIf="isValid;then content"></div>    
<ng-template #content>content here...</ng-template>

Details:

<ng-template>: is Angular’s own implementation of the <template> tag which is according to MDN :

The HTML <template> element is a mechanism for holding client-side
content that is not to be rendered when a page is loaded but may
subsequently be instantiated during runtime using JavaScript.
