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]]! > ![[Engelbart.jpg]] ### 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. > [!note] > Lorem ipsum dolor sit amet > [!abstract] > Lorem ipsum dolor sit amet Aliases: `summary`, `tldr` > [!info] > Lorem ipsum dolor sit amet > [!todo] > Lorem ipsum dolor sit amet > [!tip] > Lorem ipsum dolor sit amet Aliases: `hint`, `important` > [!success] > Lorem ipsum dolor sit amet Aliases: `check`, `done` > [!question] > Lorem ipsum dolor sit amet Aliases: `help`, `faq` > [!warning] > Lorem ipsum dolor sit amet Aliases: `caution`, `attention` > [!failure] > Lorem ipsum dolor sit amet Aliases: `fail`, `missing` > [!danger] > Lorem ipsum dolor sit amet Alias: `error` > [!bug] > Lorem ipsum dolor sit amet > [!example] > Lorem ipsum dolor sit amet > [!quote] > Lorem ipsum dolor sit amet Alias: `cite`
