Grav Markdown Collapsible Plugin

The markdown-collapsible plugin for Grav allows generation of collapsible blocks of text via markdown:

Some title

The main text goes here

The plugin is shamelessly inspired by Markdown notices

Installation

This plugin is easy to install with GPM.

$ bin/gpm install markdown-collapsible

Configuration

Simply copy the user/plugins/markdown-collapsible/markdown-collapsible.yaml into user/config/plugins/markdown-collapsible.yaml and make your modifications.

enabled: true
built_in_css: true
do_autoscroll: true
scroll_offset: 0

Automatic scroll-to-content

The default behaviour is to smooth-scroll the viewport to the top of the new content when a collapsible section is opened. To disable this, set the do_autoscroll configuration item to false.

An optional viewport-top offset (in pixels) can be specified to support themes with a sticky header or other visual effects.

Examples

A collapsible section is made of a title and some content that's initially hidden and appears when it's clicked. It requires two tags: !> for the title and !@ for the end of the content. The content can contains markdown by itself.

!> My section

### Whatever markdown you need

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris feugiat quam erat, ut iaculis diam posuere nec.
Vestibulum eu condimentum urna. Vestibulum feugiat odio ut sodales porta. Donec sit amet ante mi. Donec lobortis
orci dolor. Donec tristique volutpat ultricies. Nullam tempus, enim sit amet fringilla facilisis, ipsum ex
tincidunt ipsum, vel placerat sem sem vitae risus. Aenean posuere sed purus nec pretium.
!@

You will output the following HTML:

<input type="checkbox" id="my-section">
<label for="my-section">My section</label>
<div class="collapsible">
    <h3> Whatever markdown you need </h3>
    <p>
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris feugiat quam erat, ut iaculis diam posuere nec.
        Vestibulum eu condimentum urna. Vestibulum feugiat odio ut sodales porta. Donec sit amet ante mi. Donec lobortis
        orci dolor. Donec tristique volutpat ultricies. Nullam tempus, enim sit amet fringilla facilisis, ipsum ex
        tincidunt ipsum, vel placerat sem sem vitae risus. Aenean posuere sed purus nec pretium.
    </p>
</div>

If you want an accordion style (that is, only a single section is opened at a time), you'll use the special syntax: !>[name] My section. All sections declared with the same name will fold/unfold so only one is visible at a time (i.e. an accordion).
