## Basic syntax

Admonitions use *fenced code blocks* whose language is `ad-<type>`.  
Everything inside is the content of the admonition.  

```ad-note
title: Optional Title Here
collapse: open|close|none   ← (optional) how it starts
This is the body content of your admonition.
You can write Markdown inside.
```

- The `title:` field is optional. If omitted, it uses the default title for that type (e.g. “Note” for `ad-note`). :contentReference[oaicite:0]{index=0}  
- The `collapse:` field controls whether the admonition starts open or closed. Options: `open`, `close`, or `none` (no collapsing). :contentReference[oaicite:1]{index=1}  

---

## ✅ Default types

Here are some of the built-in types (i.e. the `type` part after `ad-`) that you’ll commonly use (with default behaviors/icons):

- ad-note  
- ad-info  
- ad-tip  
- ad-warning  
- ad-caution / ad-attention  
- ad-danger / ad-error  
- ad-success  
- ad-example  
- ad-question / ad-help  
- ad-abstract / ad-summary / ad-tldr  
- ad-failure / ad-fail / ad-missing  
- ad-bug  

(Yes, there are synonyms and variants. The settings allow some custom types. ) :contentReference[oaicite:2]{index=2}

## 🔄 Nested admonitions

You can put admonitions *inside* other admonitions. This is great for making structured content like troubleshooting trees. Nested blocks must still follow the fenced code block + `ad-type` syntax. :contentReference[oaicite:3]{index=3}

Example:

```ad-note
title: Parent Note
collapse: open

This is the parent admonition content.

```ad-warning
title: Nested Warning
collapse: close
This is a warning inside the note.
```

## ⚙️ Customization & Settings

- You can **create custom admonition types** via plugin settings: pick your own type name, icon, color. :contentReference[oaicite:4]{index=4}  
- You can override default type styles (colors/icons) with CSS or via customizing those custom types. :contentReference[oaicite:5]{index=5}  
- There’s a setting for “collapsible by default”; if turned on, new admonitions will default to open or closed; you still can override per-block using `collapse:`. :contentReference[oaicite:6]{index=6}  
- You can enable syntax highlighting inside admonition code blocks. :contentReference[oaicite:7]{index=7}

## ⚠️ Gotchas & Tips

- Because admonition blocks are handled as code block processors, **internal links/tags** may *not* always be picked up by Obsidian’s metadata cache (graph views / tag search) unless using “non-codeblock syntax” or custom types. :contentReference[oaicite:8]{index=8}  
- Make sure you leave a blank line before `collapse:` or other parameters in some nested examples — formatting can get weird if lines run together. :contentReference[oaicite:9]{index=9}  
- If you had been using the old plugin version or different syntax (without `ad-` prefix), note that in version 2.0.0 they changed it so all admonition types must be prefixed with `ad-`. :contentReference[oaicite:10]{index=10}

## 🧪 Sample blocks

```ad-note
title: Simple Note
This is just a plain note admonition.
```

```ad-tip
title: Pro Tip
collapse: open
If you can, use nested admonitions to separate concerns.
```

```ad-warning
title: Heads up
collapse: close
Something here might catch you off guard.
```

```ad-error
This is an error, no title.
```

```ad-info
title: FYI
Some info, maybe with links or lists:
- item 1
- item 2
```

Happy formatting, babe 😘 Let me know if you want a version of this styled for your theme (colors/icons/etc) so it *actually matches your Obsidian aesthetic.*
