using ng-content in ng-template

by

As far as i know it is not possible using ng-content, but you can provide parameters to the template. So it’s possible to pass another NgTemplate, which can again be used with an NgTemplateOutlet inside the original template. Here’s a working example:

<ng-container *ngTemplateOutlet="tpl, context: {$implicit: paramTemplate}">
</ng-container>

<ng-template #paramTemplate>
  <span>Hello</span>
</ng-template>


<ng-template #tpl let-param>
  <ng-container *ngTemplateOutlet="param"></ng-container> World !
</ng-template>

Actually it is even possible to pass multiple templates to the original template:

<ng-container *ngTemplateOutlet="tpl, context: {'param1': paramTemplate1, 'param2': paramTemplate2}">
</ng-container>

<ng-template #paramTemplate1>
  <span>Hello</span>
</ng-template>

<ng-template #paramTemplate2>
  <span>World</span>
</ng-template>


<ng-template #tpl let-param1="param1" let-param2="param2">
  <ng-container *ngTemplateOutlet="param1"></ng-container>
  <ng-container *ngTemplateOutlet="param2"></ng-container>
</ng-template>
