<h1>Expandable sections</h1>
|
|
|
|
<p>In some cases, where there is a lot of content, it’s helpful to collapse certain sections. That way, readers get an overview of what’s in the content and can choose where to focus in. <strong>Infusion</strong> provides a shortcode method for creating expandable sections which generates accessible markup using <code>aria-expanded</code>.</p>
|
|
|
|
<p>The <code>expandable</code> shortcode takes three parameters:</p>
|
|
|
|
<ul>
|
|
<li><strong>label</strong> — This is the label for the the section heading.</li>
|
|
<li><strong>level</strong> — This is the heading level (e.g. <code>2</code> or <code><h2></code>) that will contain the label. If you omit a level parameter, no heading is used; it’s just a button</li>
|
|
<li><strong>open</strong> — Include this and give it a value of “true” or “yes” to make the section expanded on page load</li>
|
|
</ul>
|
|
|
|
<p>Here’s what the code might look like for a simple expandable section containing markdown:</p>
|
|
|
|
<pre class=" "><code data-codeblock-shortcode>
|
|
{{% expandable label="A section of dummy text" level="2" %}}
|
|

<p>Unfortunately, it is not currently possible to include shortcodes inside other shortcodes, using the “<code>%</code>” notation (which is designated for markdown content). If you use the angle brackets notation (illustrated below) it is possible, but markdown will no longer be permitted. You will have to code HTML inside such a section manually.</p>
