MediaArt

This plugin provides shortcodes to show/hide content with an optional accordion behavior:
<ul>
<li>New shortcode: <code>[ma_collapse]...[/ma_collapse]</code> (and <code>ma_collapse_level2..7</code>)</li>
<li>Legacy compatibility: Keeps legacy <code>bg_collapse*</code> shortcodes functional (where possible without breaking other installed plugins).</li>
</ul>
The plugin is written to follow WordPress.org best practices: 
* No inline JavaScript in PHP templates 
* Admin actions protected by capability checks and nonces 
* Sanitization/escaping on output 
* Translatable strings (EN as base; Czech translation included)
<h3>Usage</h3>
Basic: 
 [ma_collapse]Hidden content[/ma_collapse]
With custom label: 
 [ma_collapse more=”Show more” less=”Show less”]Hidden content[/ma_collapse]
Accordion grouping: 
Use the same <code>group</code> attribute on multiple shortcodes. 
 [ma_collapse group=”faq”]Item 1[/ma_collapse] [ma_collapse group=”faq”]Item 2[/ma_collapse]
Legacy: 
 [bg_collapse]Hidden content[/bg_collapse]
