ReformBox extends WordPress Lightbox functionality beyond images. It currently supports Group, Paragraph, and Video blocks with poster images directly, while delegating Image lightbox behavior to WordPress core. For <code>core/image</code>, ReformBox only syncs the sidebar toggle with core lightbox settings.
<a href="https://github.com/tbshiki/reformbox" rel="nofollow ugc">This plugin is developed on GitHub.</a>
Supported Blocks:
<ul>
<li>Image Block – Uses WordPress core lightbox behavior (ReformBox panel toggles core <code>lightbox.enabled</code>)</li>
<li>Video Block – Opens in a lightbox when a poster image is set (poster acts as the click trigger)</li>
<li>Group Block – Supports both <code>same</code> mode (same content in page + modal) and <code>split</code> mode (separate Preview/Modal direct child Group slots)</li>
<li>Paragraph Block – Click to open itself in a lightbox</li>
</ul>
Features:
<ul>
<li>No-code lightbox creation via block editor controls</li>
<li>Core-first image lightbox integration (<code>core/image</code>)</li>
<li>Core-aligned overlay markup for custom lightboxes</li>
<li>Core-aligned zoom animation</li>
<li>ESC key and overlay click to close</li>
<li>Accessible (ARIA attributes, focus management, keyboard navigation)</li>
<li>Group split mode with Preview/Modal slot mapping</li>
<li>Safe split fallback: if no Modal slot is assigned, Preview content is used</li>
<li>Lazy-loaded assets (CSS/JS only loaded when needed)</li>
<li>Self-lightbox videos defer preload/autoplay until opened</li>
<li>Core image workflow integration without overriding core image rendering</li>
<li>Global overlay background color and opacity controls in Settings > ReformBox</li>
<li>Plugin list row includes a Settings action link for quick access</li>
<li>Lightweight and performant</li>
</ul>
