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]

Simple plugin to show/hide comment replies, rather than have them all listed. An options page makes it really easy to change different parts of your comment calls.
<h4>Features</h4>
This keeps the default “<a href="https://codex.wordpress.org/Function_Reference/wp_list_comments" rel="nofollow ugc"><code>wp_list_comments()</code></a>” features. A clickable span that triggers the action to expand the replies is also added.
New features are including easing options, as well as allowing images. An options page has been added for further customizations, making it even easier to use.
<h3>Other Info</h3>
<h4>Known Issues</h4>
None at this time.

Given that this is free, I offer limited support. If you have issues with the plugin working I will do whatever I can to help you fix the issue, but when it comes to customization, I’m in limited supply. I’ll do what I can, but no guarantees. This is your standard “as is” application. In all honesty, ask customization questions in the forums – if I can’t help, perhaps someone else can. (If you want to hire me to customize it, that’s another story – feel free to contact me to do so!)
PLEASE NOTE that the WordPress support system DOES NOT notify me when someone leaves a support question. It requires me to come back and check manually to see if anyone has had an issue. Sometimes, I don’t get to do that for a while. If you left a support request on the forums, and it’s been at least a week since you left it with no response, please drop me an email to let me know so I can attempt to help you out. I’m pretty good at helping out – but I’m not so good at coming to check the forums – especially when I’m busy with client work.
