[Fixed] Multiple ng-content

Issue

I am trying to build a custom component using multiple ng-content in Angular 6, but this is not working and I have no idea why.

This is my component code:

<div class="header-css-class">
    <ng-content select="#header"></ng-content>
</div>
<div class="body-css-class">
    <ng-content select="#body"></ng-content>
</div>

I am trying to use this component in another place and render two different HTML code inside body and header select of ng-content, something like this:

<div #header>This should be rendered in header selection of ng-content</div>
<div #body>This should be rendered in body selection of ng-content</div>

But the component is rendering blank.

Do you guys know what I could be doing wrong or what is the best way to render two different sections in same component?

Thanks!

Solution

  1. You could add dummy attributes header and body as opposed to template references (#header, #body).
  2. And transclude using ng-content with select attribute like select="[header]".

app.comp.html

<app-child>
    <div header >This should be rendered in header selection of ng-content</div>
    <div body >This should be rendered in body selection of ng-content</div>
</app-child>

child.comp.html

<div class="header-css-class">
    <ng-content select="[header]"></ng-content>
</div>
<div class="body-css-class">
    <ng-content select="[body]"></ng-content>
</div>
