Working with ng-content on Storybook

Very often when creating a new story for an Angular component on Storybook you might need to insert content into components which have an ng-content area inside them.

To do that you need to create a template for your story.

Here is a simple component, which has a div with and an ng-content area inside it. The component has two inputs, width and height.

// paper.component.ts
import { Component, Input } from '@angular/core';

  selector: 'cx-paper',
  template: `
    <div class="paper" [ngStyle]="{ width: width, height: height }">
  styles: [
      .paper {
        border: navy solid 2px;
        padding: 10px;
export class PaperComponent {
  width: string;

  height: string;
Enter fullscreen mode Exit fullscreen mode

The story for this component

// paper.stories.ts
import { Story, Meta } from '@storybook/angular';
import { PaperComponent } from './paper.component';

export default {
  title: 'Example/Paper',
  component: PaperComponent,
} as Meta;

const Template: Story<PaperComponent> = (args: PaperComponent) => ({
  props: args,
  template: `
  <cx-paper [height]="height" [width]="width">
  This is a template test.

export const SimpleExample = Template.bind({});

SimpleExample.args = {
  height: '50px',
  width: '300px',
} as Partial<PaperComponent>;
Enter fullscreen mode Exit fullscreen mode

Which should render like this:

Why the show code part is not showing the content?
This text is missing in the code: "This is a template test."

Now this works for writing stories but it doesn't work right with the ArgsTable and doesn't show any output actions for me at least :z

If by ArgsTable you mean the component inputs, it's working fine for me. I change the inputs and can see the component respond to those changes. I haven't been able to figure out how to make Actions work with a template like that yet.

ArgTable works in the story view but doesn’t in the docs view / docs page.
If this actually works someday that would be very nice but right now storybook for angular is such a pain :z
