<p>A single shortcode you can drop into any post, page, or text widget to get a click-to-expand “read more” toggle. The output is a native HTML <code><details></code> element styled with a small inline stylesheet — nothing else.</p>
<p>The point is the absence of features. There is no settings page, no animation library, no editor block panel with twelve toggles. If you need a read-more on one paragraph in one post, you do not want a plugin that wants to manage your whole site.</p>
<p>Usage:</p>
<pre><code>[expand title="My title"]
The content goes here.
<img src="even-images-can-go-in-here.jpg" />
And wrap up with a closing expand tag.
[/expand]
</code></pre>
<p>Supports a custom CSS class via <code>[expand class="my-class"]</code> and works with WordPress oEmbeds and other shortcodes nested inside.</p>

<p>nnax ReadMore helps editors keep posts and pages compact while still making additional content available on demand.</p>
<p>Use the shortcode <code>[nnax_readmore]...[/nnax_readmore]</code> to hide longer sections behind a toggle button. Visitors can expand and collapse the content without requiring a bundled frontend framework.</p>
<h4>Main features</h4>
<ul>
<li>Namespaced shortcode <code>[nnax_readmore]</code> for expandable content blocks</li>
<li>Dedicated ReadMore block for Gutenberg and a button above the editor in the Classic Editor</li>
<li>Toggle button text between “Mehr anzeigen” and “Weniger anzeigen”</li>
<li>Configurable button CSS classes in plugin settings</li>
<li>Role-based visibility and editing permissions for the plugin admin area</li>
<li>Toggle behavior works without any bundled frontend library</li>
<li>Clean uninstall behavior for plugin options</li>
</ul>
<h3>Requirements</h3>
<ul>
<li>WordPress 6.0 or higher</li>
<li>PHP 7.4 or higher</li>
</ul>
<h3>Usage</h3>
<p>Use this shortcode in content:</p>
<pre><code>[nnax_readmore]Your hidden content[/nnax_readmore]
</code></pre>
<p>In Gutenberg, a dedicated <code>ReadMore</code> block is available in the block inserter. In the Classic Editor, the button is available above the editor. In both cases, a dialog opens for entering the hidden content.</p>
<h3>Uninstallation</h3>
<p>When the plugin is deleted, <code>uninstall.php</code> removes the options <code>nnaxreadmore_button_classes</code>, <code>nnaxreadmore_general_settings</code>, and <code>nnaxreadmore_role_access</code>.<br />
In multisite, cleanup runs per site and also removes a possible network option.</p>
<h3>Known Limitations</h3>
<ul>
<li>The plugin focuses on the shortcode toggle behavior only.</li>
<li>Runtime compatibility with the minimum supported WordPress version, multisite setups, and broader theme sets must be validated in the target project environment.</li>
</ul>
