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>level="2"</code> for a <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" %}}
|
|
Here is some markdown including [a link](https://twitter.com/heydonworks). Donec erat est, feugiat a est sed, aliquet pharetra ipsum. Vivamus in arcu leo. Praesent feugiat, purus a molestie ultrices, libero massa iaculis ante, sit amet accumsan leo eros vel ligula.
|
|
{{% /expandable %}}
|
|
</code></pre>
|
|
|
|
|
|
<p>Let’s look at what that outputs:</p>
|
|
|
