About this plugin
Collapsi for the Block Editor 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.
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 strictly editor-only — your published site is untouched, no extra CSS or JS ships to the frontend.
Why this plugin
- Stop scrolling endlessly. Collapse the sections you’re not working on. Find the one you are in seconds.
- Works on every block. Core, third-party, custom, ACF — anything Gutenberg renders, Collapsi can collapse.
- Survives reloads. Collapse state is saved per post, per template, per browser. Come back tomorrow, your layout is where you left it.
- Per-instance opt-out. Set “Never collapse this block” on a hero or any pinned block from the block settings menu.
- Keyboard shortcut. Alt+Shift+C toggles all top-level blocks at once. Discoverable in WP’s shortcut help modal (? ).
- No telemetry. No remote calls. No premium upsell. Free, GPL, forever.
