No Preview

Sorry, but you either have no stories or none are selected somehow.

If the problem persists, check the browser console, or the terminal you've run Storybook from.

The component failed to render properly, likely due to a configuration issue in Storybook. Here are some common causes and how you can address them:

  1. Missing Context/Providers: You can use decorators to supply specific contexts or providers, which are sometimes necessary for components to render correctly. For detailed instructions on using decorators, please visit the Decorators documentation.
  2. Misconfigured Webpack or Vite: Verify that Storybook picks up all necessary settings for loaders, plugins, and other relevant parameters. You can find step-by-step guides for configuring Webpack or Vite with Storybook.
  3. Missing Environment Variables: Your Storybook may require specific environment variables to function as intended. You can set up custom environment variables as outlined in the Environment Variables documentation.

Collapsible

Toggle the visibility of content across your project.

The <post-collapsible> component is used to show and hide content. Collapsing an element will animate the height from its current value to 0.

Contentus momentus vero siteos et accusam iretea et justo.

 
<post-collapsible-trigger for="6a91848c-16ec-4a23-bc45-51c797b5b2c3--default">
  <button class="btn btn-secondary">Toggle Collapsible</button>
</post-collapsible-trigger>

<post-collapsible id="6a91848c-16ec-4a23-bc45-51c797b5b2c3--default">
  <p class="border rounded p-large">Contentus momentus vero siteos et accusam iretea et justo.</p>

The following examples show different use cases for the <post-collapsible> component.

To make the collapsible content hidden by default, just use the collapsible="true" property.

Contentus momentus vero siteos et accusam iretea et justo.

The <post-collapsible> component offers a .toggle() method that allows you to trigger the collapse programmatically. This method is asynchronous and returns a promise that resolves with the current open state. It optionally takes a boolean parameter: true forces it open, and false forces it closed.

const collapsible = document.querySelector('#collapsibleId') as HTMLPostCollapsibleElement;
collapsible.toggle(/* open: boolean */).then((/* isOpen: boolean */) => {});
