Ju'Z[ed]

<p>JuZ Rich Text Extender allows developers to register custom inline format buttons in the Gutenberg (block editor) toolbar. Each button applies a specific HTML inline tag with an optional CSS class to the selected text.</p>
<p>The plugin includes a built-in nesting validation system: buttons are automatically disabled when their use would produce invalid HTML nesting (e.g. <code><a></code> inside <code><a></code>). When a format is already active, its button remains enabled so it can always be toggled off.</p>
<p><strong>Key features:</strong></p>
<ul>
<li>Register custom inline formats (tag + CSS class) via a WordPress filter</li>
<li><code>tagName</code> defaults to <code>span</code>, which is strongly recommended for compatibility</li>
<li>Smart nesting validation against the full active tag stack (for non-span tags)</li>
<li>Buttons are visually disabled when nesting is not allowed</li>
<li>Exhaustive inline tag ruleset (<code>span</code>, <code>a</code>, <code>strong</code>, <code>em</code>, <code>mark</code>, <code>code</code>, <code>u</code>, <code>s</code>, <code>i</code>, <code>b</code>, <code>q</code>, <code>cite</code>, <code>abbr</code>, <code>small</code>, <code>sub</code>, <code>sup</code>)</li>
<li>Inline tag rules are filterable for full customisation by themes or other plugins</li>
</ul>
<p><strong>For developers:</strong></p>
<p>Formats and inline tag rules are both exposed via WordPress filters, making the plugin fully extensible without modifying core files.</p>
