Angular 6 multiple ng-content

Question

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 differents 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!

Answer 1

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>

alternatively you can use:

app.comp.html

<app-child>
    <div role="header">This should be rendered in header selection of ng-content</div>
    <div role="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="div[role=header]"></ng-content>
</div>
<div class="body-css-class">
    <ng-content select="div[role=body]"></ng-content>
</div>
