If you really would like Extra to include additional extensions, we suggest creating your own clone of Extra under a different name (see the [Extension API](api.html)). + +Markdown Inside HTML Blocks +--------------------------- + +Unlike the other Extra features, this feature is build into the markdown core and is turned on when `extra` is enabled. + +The content of any block-level element can be Markdown-formatted simply by adding a `markdown` attribute to the opening tag. The markdown attribute will be stripped from the output, but all other attributes will be preserved. + +If the markdown value is set to `1` (recommended) or any value other than `span` or `block`, the default behavior will be executed: `p`,`h[1-6]`,`li`,`dd`,`dt`,`td`,`th`,`legend`, and `address` elements skip block parsing while others do not. If the default is overrident by a value of `span`, *block parsing will be skipped* regardless of tag. If the default is overriden by a value of `block`, *block parsing will occur* regardless of tag. + +*An opening tag with the markdown attribute must start immediately on a line following a blank line.* + +#### Simple Example: +``` +This is *true* markdown text. + +<div markdown="1"> +This is *true* markdown text. +</div> +``` +#### Result: +``` +<p>This is <em>true</em> markdown text.</p> +<div> +<p>This is <em>true</em> markdown text.</p> +</div> +``` + +### Nested Markdown Inside HTML BLocks +Nested elements are more sensitive and must be used cautiously. Violation of the following will lead to unexpected behavior or unhandled exceptions. + * Only block mode elements may have further elements nested within them. + * The closing tag of inner elements must be followed by a blank line. + * More than one level of nesting is not supported (i.e., elements nested within elements nested within elements). This feature is not an alternative to templating. + +#### Complex Example: +``` +<div markdown="1" name="Example"> + +The text of the `Example` element. + +<div markdown="1" name="DefaultBlockMode"> +This text gets wrapped in `p` tags. +</div> + +The tail of the `DefaultBlockMode` subelement. + +<p markdown="1" name="DefaultSpanMode"> +This text *is not* wrapped in additional `p` tags. +</p> + +The tail of the `DefaultSpanMode` subelement. + +<div markdown="span" name="SpanModeOverride"> +This `div` block is not wrapped in paragraph tags. +Note: Subelements are not required to have tail text. +</div> + +<p markdown="block" name="BlockModeOverride"> +This `p` block *is* foolishly wrapped in further paragraph tags. +</p> + +The tail of the `BlockModeOverride` subelement. + +<div name="RawHtml"> +Raw html blocks may also be nested. +</div> + +</div> + +This text is after the markdown in html. +``` +#### Result: +``` +<div name="Example"> +<p>The text of the <code>Example</code> element.</p> +<div name="DefaultBlockMode"> +<p>This text gets wrapped in <code>p</code> tags.</p> +</div> +<p>The tail of the <code>DefaultBlockMode</code> subelement.</p> +<p name="DefaultSpanMode"> +This text <em>is not</em> wrapped in additional <code>p</code> tags.</p> +<p>The tail of the <code>DefaultSpanMode</code> subelement.</p> +<div name="SpanModeOverride"> +This <code>div</code> block is not wrapped in paragraph tags. +Note: Subelements are not required to have tail text.</div> +<p name="BlockModeOverride"> +<p>This <code>p</code> block <em>is</em> foolishly wrapped in further paragraph tags.</p> +</p> +<p>The tail of the <code>BlockModeOverride</code> subelement.</p> +<div name="RawHtml"> +Raw html blocks may also be nested. +</div> + +</div> +<p>This text is after the markdown in html.</p> +``` |
