Markdown

A showcase of all Markdown features supported in Trilium's Markdown note type.

1. Basic Formatting (Standard Markdown)

Bold text, italic text, ~~strikethrough~~, and inline code.

A simple blockquote demonstrating standard Markdown.

2. GitHub-Flavored Markdown (GFM)

Tables

Feature	Supported	Notes
Standard Markdown	✅	Full support
GFM Tables	✅	Like this one
Math Equations	✅	Via KaTeX
Mermaid Diagrams	✅	Via ```mermaid blocks
Admonitions	✅	GitHub-style

Task Lists

Create a Markdown note in Trilium
Add syntax highlighting
Convert from a Text note
Export and re-import

3. Code Blocks with Syntax Highlighting

Note: The language must be specified for syntax highlighting to apply.

Sample with no syntax highlighting:

function greet(name) {

  return `Hello, ${name}!`;

}

console.log(greet("Trilium"));

JavaScript with syntax highlighting:

// JavaScript example

function greet(name) {

  return `Hello, ${name}!`;

}

console.log(greet("Trilium"));

Python example:

def factorial(n):

    return 1 if n <= 1 else n * factorial(n - 1)



print(factorial(10))

SQL example:

SELECT title, dateCreated

FROM notes

WHERE type = 'markdown'

ORDER BY dateCreated DESC;

4. Block Quotes & Admonitions

A standard Markdown blockquote. It can span multiple lines.

5. Math Equations

Inline math: \(E = mc^2\)

Block math:

\[\int_{-\infty}^{\infty} e^{-x^2} \, dx = \sqrt{\pi}\] \[\Gamma(n) = (n-1)! \quad \forall n \in \mathbb{N}\]

6. Mermaid Diagrams

7. Internal (Reference) Links — Wikilinks Format

Link to a note by its Note ID using the Wikilinks-like format:

[missing note]

Or using HTML syntax for more control:

Internal link via HTML

8. Include Note (HTML Syntax)

Included notes using HTML syntax.

9. Nested Syntax Highlighting (Code Inside Code Blocks)

Trilium's source pane supports nested syntax highlighting — for example, highlighting HTML inside a Markdown code fence:

<!DOCTYPE html>

<html lang="en">

<head>

  <meta charset="UTF-8">

  <title>Trilium</title>

</head>

<body>

  <h1>Hello from HTML inside Markdown!</h1>

</body>

</html>
