Use callouts to include additional content without breaking the flow of your notes.
To create a callout, add `[!info]` to the first line of a blockquote, where `info` is the *type identifier*. The type identifier determines how the callout looks and feels. To see all available types, refer to [Supported types](https://help.obsidian.md/Editing+and+formatting/Callouts#Supported%20types).
> [!info]
> Here's a callout block.
> It supports ****, [[Internal link|Wikilinks]], and [[Embed files|embeds]]!

### Change the 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:
> [!tip] Callouts can have custom titles
> Like this one.
Callouts can have custom titles
Like this one.
You can even omit the body to create title-only callouts:
> [!tip] Title-only callout
### Foldable callouts
You can make a callout foldable by adding a plus (+) or a minus (-) directly after the type identifier.
A plus sign expands the callout by default, and a minus sign collapses it instead.
> [!faq]- Are callouts foldable?
> Yes! In a foldable callout, the contents are hidden when the callout is collapsed.
### Nested callouts
> [!question] Can callouts be nested?
> > [!todo] Yes!, they can.
> > > [!example] You can even use multiple layers of nesting.
### Supported types
You can use several callout types and aliases. Each type comes with a different background color and icon.
To use these default styles, replace `info` in the examples with any of these types, such as `[!tip]` or `[!warning]`. Callout types can also be changed by right-clicking a callout.
Unless you [Customize callouts](https://help.obsidian.md/Editing+and+formatting/Callouts#Customize%20callouts), any unsupported type defaults to the `note` type. The type identifier is case-insensitive.
