<p><strong>Collapsi for the Block Editor</strong> adds an editor-only chevron toggle to every Gutenberg block. Hover any top-level block, click the chevron, and the block tucks away into a compact bar showing the block’s icon, title, and a short content preview (paragraph text, image alt, “5 blocks”, and so on). Toggle it back open with the same chevron.</p>
<p>Built for the long pages and Site Editor templates where scrolling past 50 blocks to find the one you want is the daily annoyance. Collapsi is <strong>strictly editor-only</strong> — your published site is untouched, no extra CSS or JS ships to the frontend.</p>
<h4>Why this plugin</h4>
<ul>
<li><strong>Stop scrolling endlessly.</strong> Collapse the sections you’re not working on. Find the one you are in seconds.</li>
<li><strong>Works on every block.</strong> Core, third-party, custom, ACF — anything Gutenberg renders, Collapsi can collapse.</li>
<li><strong>Survives reloads.</strong> Collapse state is saved per post, per template, per browser. Come back tomorrow, your layout is where you left it.</li>
<li><strong>Per-instance opt-out.</strong> Set “Never collapse this block” on a hero or any pinned block from the block settings menu.</li>
<li><strong>Keyboard shortcut.</strong> <code>Alt+Shift+C</code> toggles all top-level blocks at once. Discoverable in WP’s shortcut help modal (<code>?</code>).</li>
<li><strong>No telemetry. No remote calls. No premium upsell.</strong> Free, GPL, forever.</li>
</ul>
<h4>How it works</h4>
<p>The plugin hooks <code>editor.BlockListBlock</code> with a higher-order component that wraps every top-level block. State lives in a <code>@wordpress/data</code> store and persists to <code>localStorage</code> keyed by either the block’s structural path (<code>"0.2.1"</code>) or its user-set name from Gutenberg’s rename feature. A <code>PluginSidebar</code> exposes Collapse All / Expand All / Focus Mode. Settings live at <code>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Collapsi</code> and persist via the REST API.</p>
<h4>Compatibility</h4>
<ul>
<li>WordPress 6.5+ (iframed editor)</li>
<li>PHP 7.4+</li>
<li>Post Editor and Site Editor</li>
<li>Browsers: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+</li>
</ul>
<h4>Not in scope</h4>
<ul>
<li>No Classic Editor support — Gutenberg only</li>
<li>No frontend collapse (this is an editor productivity plugin, not a UX framework)</li>
<li>No premium tier</li>
</ul>
<h3>Development</h3>
<p>Source code, issue tracker, and build instructions live at https://github.com/devMoaz/collapsi-for-block-editor. The compiled assets in <code>build/</code> are produced by <code>@wordpress/scripts</code> (webpack) from the <code>src/</code> directory in the GitHub repository. Run <code>npm install && npm run build</code> to reproduce.</p>

<h4>What this plugin is:</h4>
<p>This plugin is designed for use with the Advanced Custom Fields Plugin – Repeater add on. Collapses all advanced custom field repeater rows by default and adds accordion functionality to them for easy editing. Only tested with repeater rows.</p>
<p>If you are using the repeater plugin add on you will probably notice that the paged view becomes quite cumbersome as you add more entires using the repeater fields. It becomes very difficult to drag fields up or down and the page becomes very long.</p>
<p>This plugin is the answer to make editing easier.</p>
<h4>What this plugin is not:</h4>
<p>This plugin is not intended to create accordion functionality on the website. It is only meant to make the page edit view easier to work with.</p>
