The `mermaid` shortcode generates diagrams and flowcharts from text in a similar manner as Markdown using the [Mermaid](https://mermaidjs.github.io/) library.

````mermaid {align="center" zoom="true"}
graph LR;
  If --> Then
  Then --> Else
````

## Usage

{{< tabs groupid="shortcode-parameter">}}
{{% tab title="codefence" %}}

````md
```mermaid {align="center" zoom="true"}
graph LR;
  If --> Then
  Then --> Else
```
````

{{% /tab %}}
{{% tab title="shortcode" %}}

````go
{{</* mermaid align="center" zoom="true" */>}}
graph LR;
  If --> Then
  Then --> Else
{{</* /mermaid */>}}
````

{{% /tab %}}
{{% tab title="partial" %}}

````go
{{ partial "shortcodes/mermaid.html" (dict
  "page"    .
  "content" "graph LR;\n  If --> Then\n  Then --> Else"
  "align"   "center"
  "zoom"    "true"
)}}

````

Codefence syntax is widely available in other Markdown parsers like GitHub and therefore is the recommend syntax for generating portable Markdown.

### Parameter

| Name                  | Default          | Notes       |
|-----------------------|------------------|-------------|
| **align**             | `center`         | The vertical alignment.<br><br>Allowed values are `left`, `center` or `right`. |
| **zoom**              | see notes        | Whether the graph is pan- and zoomable.<br><br>If not set the value is determined by the [`mermaidZoom` setting](#configuring-pan-and-zoom) of your configurations options or the pages front matter or `false` if not set at all.<br><br>- `false`: no pan or zoom<br>- `true`: pan and zoom active |
| _**&lt;content&gt;**_ | _&lt;empty&gt;_  | Your Mermaid graph. |

## Settings

### Configuring Pan and Zoom

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} {{% badge style="green" icon="fa-fw fab fa-markdown" title=" " %}}Front Matter{{% /badge %}} The generated graphs can be panned by dragging them and zoomed by using the mousewheel. On mobile devices you can use finger gestures.

By default this is disabled. Set `mermaidZoom=true` to enable it.

Individual settings of a graphs [`zoom` parameter](#parameter) have precedence over the page's front matter and configuration options in that order.

{{< multiconfig >}}
mermaidZoom = true
{{< /multiconfig >}}

### Providing Initialization Options for the Mermaid Library

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} {{% badge style="green" icon="fa-fw fab fa-markdown" title=" " %}}Front Matter{{% /badge %}} The Mermaid library is configured with default settings for initialization.

You can overwrite the settings by providing a JSON object in `mermaidInitialize`. See [Mermaid's documentation](https://mermaid-js.github.io/mermaid/#/Setup?id=mermaidapi-configuration-defaults) for all allowed settings.

Keep in mind that initialization settings of your pages front matter overwrite all settings of your configuration options.

In addition, you can merge settings for each individual graph through [diagram directives](https://mermaid-js.github.io/mermaid/#/directives?id=directives) on top of the settings of your page's front matter or configuration options.

{{< multiconfig >}}
mermaidInitialize = '{ "securityLevel": "loose" }'
{{< /multiconfig >}}

### Loading an External Version of the Mermaid Library

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} {{% badge style="green" icon="fa-fw fab fa-markdown" title=" " %}}Front Matter{{% /badge %}} The theme uses the shipped Mermaid library by default.

In case you want do use a different version of the Mermaid library but don't want to override the shipped version, you can set `customMermaidURL` to the URL of the external Mermaid library.

{{< multiconfig >}}
customMermaidURL = 'https://unpkg.com/mermaid/dist/mermaid.min.js'
{{< /multiconfig >}}

### Force Loading of the Mermaid Library

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} {{% badge style="green" icon="fa-fw fab fa-markdown" title=" " %}}Front Matter{{% /badge %}} The Mermaid library will be loaded if the page contains an `mermaid` shortcode or codefence.

You can force loading the Mermaid library if no shortcode or codefence was used by setting `mermaid.force=true`. If a shortcode or codefence was found, this option has no effect. This comes handy in case you are using scripting to render a graph.

{{< multiconfig >}}
mermaid.force = true
{{< /multiconfig >}}

### Setting a Specific Mermaid Theme

While you can configure the Mermaid theme to render your graph by using one of the [initialization options](#providing-initialization-options-for-the-mermaid-library), the recommended way is to set the default value using the `--MERMAID-theme` variable in your [color variant stylesheet](configuration/branding/generator). This allows your graphs to look pretty when the user switches the color variant.

## Examples
