--- icon: material/plus-circle --- # Annotations One of the flagship features of Material for MkDocs is the ability to inject annotations – little markers that can be added almost anywhere in a document and expand a tooltip containing arbitrary Markdown on click or keyboard focus. ## Configuration This configuration allows to add annotations to all inline- and block-level elements, as well as code blocks, and nest annotations inside each other. Add the following lines to `mkdocs.yml`: ``` yaml markdown_extensions: - attr_list - md_in_html - pymdownx.superfences ``` See additional configuration options: - [Attribute Lists] - [Markdown in HTML] - [SuperFences] [Attribute Lists]: ../setup/extensions/python-markdown.md#attribute-lists [Markdown in HTML]: ../setup/extensions/python-markdown.md#markdown-in-html [SuperFences]: ../setup/extensions/python-markdown-extensions.md#superfences ### Annotation icons <!-- md:version 9.2.0 --> The annotation icon can be changed to any icon bundled with the theme, or even a [custom icon], e.g. to material/arrow-right-circle:. Simply add the following lines to `mkdocs.yml`: ``` yaml theme: icon: annotation: material/arrow-right-circle # (1)! ``` 1. Enter a few keywords to find the perfect icon using our [icon search] and click on the shortcode to copy it to your clipboard: <div class="mdx-iconsearch" data-mdx-component="iconsearch"> <input class="md-input md-input--stretch mdx-iconsearch__input" placeholder="Search icon" data-mdx-component="iconsearch-query" value="material circle" /> <div class="mdx-iconsearch-result" data-mdx-component="iconsearch-result" data-mdx-mode="file"> <div class="mdx-iconsearch-result__meta"></div> <ol class="mdx-iconsearch-result__list"></ol> </div> </div> Some popular choices: - :material-plus-circle: - `material/plus-circle` - :material-circle-medium: - `material/circle-medium` - :material-record-circle: - `material/record-circle` - :material-arrow-right-circle: - `material/arrow-right-circle` - :material-arrow-right-circle-outline: - `material/arrow-right-circle-outline` - :material-chevron-right-circle: - `material/chevron-right-circle` - :material-star-four-points-circle: - `material/star-four-points-circle` - :material-plus-circle-outline: - `material/plus-circle-outline` [custom icon]: ../setup/changing-the-logo-and-icons.md#additional-icons [icon search]: icons-emojis.md#search ## Usage ### Using annotations <!-- md:version 9.2.0 --> <!-- md:flag experimental --> Annotations consist of two parts: a marker, which can be placed anywhere in a block marked with the `annotate` class, and content located in a list below the block containing the marker: ``` markdown title="Text with annotations" Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate } 1. :man_raising_hand: I'm an annotation! I can contain `code`, __formatted text__, images, ... basically anything that can be expressed in Markdown. ``` <div class="result" markdown> Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate } 1. :man_raising_hand: I'm an annotation! I can contain `code`, __formatted text__, images, ... basically anything that can be written in Markdown. </div> Note that the `annotate` class must only be added to the outermost block. All nested elements can use the same list to define annotations, except when annotations are nested themselves. #### in annotations When [SuperFences] is enabled, annotations can be nested inside annotations by adding the `annotate` class to the list item hosting the annotation content, repeating the process: ``` markdown title="Text with nested annotations" Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate } 1. :man_raising_hand: I'm an annotation! (1) { .annotate } 1. :woman_raising_hand: I'm an annotation as well! ``` <div class="result" markdown> Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate } 1. :man_raising_hand: I'm an annotation! (1) { .annotate style="margin-bottom: 0" } 1. :woman_raising_hand: I'm an annotation as well! </div> #### in admonitions The titles and bodies of [admonitions] can also host annotations by adding the `annotate` modifier after the type qualifier, which is similar to how [inline blocks] work: ``` markdown title="Admonition with annotations" !!! note annotate "Phasellus posuere in sem ut cursus (1)" Lorem ipsum dolor sit amet, (2) consectetur adipiscing elit. Nulla et euismod nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor massa, nec semper lorem quam in massa. 1. :man_raising_hand: I'm an annotation! 2. :woman_raising_hand: I'm an annotation as well! ``` <div class="result" markdown> !!! note annotate "Phasellus posuere in sem ut cursus (1)" Lorem ipsum dolor sit amet, (2) consectetur adipiscing elit. Nulla et euismod nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor massa, nec semper lorem quam in massa. 1. :man_raising_hand: I'm an annotation! 2. :woman_raising_hand: I'm an annotation as well! </div> [admonitions]: admonitions.md [inline blocks]: admonitions.md#inline-blocks #### in content tabs Content tabs can host annotations by adding the `annotate` class to the block of a dedicated content tab (and not to the container, which is not supported): ``` markdown title="Content tabs with annotations" === "Tab 1" Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate } 1. :man_raising_hand: I'm an annotation! === "Tab 2" Phasellus posuere in sem ut cursus (1) { .annotate } 1. :woman_raising_hand: I'm an annotation as well! ``` <div class="result" markdown> === "Tab 1" Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate } 1. :man_raising_hand: I'm an annotation! === "Tab 2" Phasellus posuere in sem ut cursus (1) { .annotate } 1. :woman_raising_hand: I'm an annotation as well! </div> #### in everything else The [Attribute Lists] extension is the key ingredient for adding annotations to most elements, but it has some [limitations]. However, it's always possible to leverage the [Markdown in HTML] extension to wrap arbitrary elements with a `div` with the `annotate` class: ```` html title="HTML with annotations" <div class="annotate" markdown> > Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. </div> 1. :man_raising_hand: I'm an annotation! ```` <div class="result" markdown> <div class="annotate" markdown> > Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. </div> 1. :man_raising_hand: I'm an annotation! </div> With this trick, annotations can also be added to blockquotes, lists, and many other elements that are not supported by the [Attribute Lists] extension. Furthermore, note that [code blocks follow different semantics]. !!! warning "Known limitations" Please note that annotations currently don't work in [data tables] as reported in #3453, as data tables are scrollable elements and positioning is very tricky to get right. This might be fixed in the future.
