Install this theme component

This theme component adds support for Obsidian-style callouts in Discourse as an alternative for markdown quotes.

Callouts are a great way to highlight content and add notes, warnings, or other special messages to your posts.


Usage

To create a callout, add [!type] to the first line of a quote, where type is the type identifier. The type identifier determines how the callout looks and feels. To see all available types, refer to Supported types.

:information_source: The type identifier is case-insensitive.

> [!tip] 
> **Tip**: Use `code snippets` to enhance readability. They provide clarity and precision.

Custom title

By default, the title of the callout is its type identifier in title case. You can change it by adding text after the type identifier:

> [!question] Custom Label 🤗
> Callouts labels can be customized.

> [!abstract] [date=2032-12-22 timezone="Europe/Paris"]
> They can also contain special inline formatting like dynamic dates.

You can also create title-only callouts:

> [!success] solved.

Foldable callouts

You can make a callout foldable by adding a plus + or a minus - directly after the type identifier.

  • + expands the callout by default
  • - collapses it instead
> [!todo]- My Todo List
>
> - [x] Write documentation
> - [ ] Add tests
> - [ ] Review code

> [!todo]+ My Expanded Todo List
>
> - [x] Create repository
> - [ ] Setup CI/CD
> - [ ] Deploy to production

Nested callouts

You can nest callouts in multiple levels.

> [!question] Can callouts be nested?

> > [!todo] Yes!, they can.

> > > [!example] You can even use multiple layers of nesting.

> [!tip]

> > [!info]
> > With some additional information

> Back to the main tip

Supported default types

You can use several callout types and aliases.
Each type comes with a different background color and icon.

:information_source: You can create your callouts or manage the default ones.
See the callouts setting.

:information_source: Any unsupported type defaults to the note type. See Default Fallbacks section for more information.

:information_source: The type identifier is case-insensitive.

abstract For summaries or abstract sections summary, tldr
info For informational content -

Customization

Icon

You can use either FontAwesome 6 icon or directly provide an SVG element.

SVG element

While the free FontAwesome version provides many choices, you may feel limited sometimes.
You can provide an SVG element <svg>...</svg>.

Example: Lucile icons – It’s a great set with the advantage of choosing the stroke width.

  1. Select an icon
  2. Adjust the Stroke width
  3. Click on Copy SVG
  4. Go to the theme component settings and paste the content

Default Fallbacks

  • callout_fallback_type
  • callout_fallback_icon
  • callout_fallback_color
> [!discourse is fantastic]
> Yes.

Global configuration

You can customize various aspects of the callouts through

  • Background opacity
  • Border properties (width, style, color, radius)
  • Padding
  • Title font properties (size, weight)
  • Space between icon and title

This is a stellar add. Much more than the base discussion seemed to entail(granted haven’t used Obsidian).

This looks amazing. Will the callouts be styled correctly on email as well?

What version of discourse are you running?

I am on Tests-passed(3.5 beta) and it seems fine

If you’re on Stable you may still be 3.4 or maybe earlier version as 3.4 just rolled out to stable

Ah, I haven’t upgraded recently because of the PostgreSQL stuff. I’ll report back when I do!

Not sure if that is the case… But a likely suspect as many changes have rolled out with how TC etc… structures have changed. Like the move to glimmer components.

Unfortunately, I don’t think so. It would require a plugin.

What is your current Discourse version?

I updated to the latest version and it works now.

The lack of email support unfortunately makes this unusable for our case. Most of our members are subscribed to groupts & categories and so read messages in their email. Bummer!

I might try to make a plugin version later!

This is a fantastic addition to Discourse! :heart: :heart: :heart:

That’s exactly what we are missing in Discourse core, at least the 4 most common types of callout such as info, danger, warning and success. We have been using the blockquote + emoji format for a while and we willl definitely give this one a shot :slight_smile:

Thank you for the theme component I really like it!

Unfortunately, I had to temporarily disable it as it was causing visual problems on my site and I saw the following in the console that I was able to trace back to your callouts.gjs
