    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

    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.

    Supported types

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

    Unless you Customize callouts, any unsupported type defaults to the note type. The type identifier is case-insensitive.

class Biology,Chemistry internal-link;

    If you have many nodes in your diagrams, you can use the following snippet.

    ```mermaid
graph TD

A[Biology]
B[Chemistry]

A --> B

class A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z internal-link;

    If you use special characters in your note names, you need to put the note name in double quotes.

    class "⨳ special character" internal-link

    Or, A["⨳ special character"].

    Math

    You can add math expressions to your notes using MathJax and the LaTeX notation.

    $$ \begin{vmatrix}a & b\ c & d \end{vmatrix}=ad-bc $$

    You can also inline math expressions by wrapping it in $ symbols.

    This is an inline math expression $e^{2i\pi} = 1$.

    Horizontal rule

    You can use three or more stars ***, hyphens ---, or underscore ___ on its own line to add a horizontal bar. You can also separate symbols using spaces.
