Description
Adds a button to the Gutenberg block sidebar (right) to toggle the editor sidebar to make it full-width. This plugin also allows dragging the sidebar left and right to provide a custom width.
Particularly useful if you need more space to work with the additional block options or you use ACF to populate block options.
This plugin is seamlessly integrated to look like it’s a native option to the Gutenberg interface.
In addition:
- NO ads.
- NO annoying notices/popups.
- NO code bloat.
- NO pro/paid version. (It is and always will be FREE).
Screenshots

I had 2 similar plugins for similar solutions but this one is even better. 5 stars and thank you. Thanks to this and similar plugins I don’t have to change the layouts of my ACF Pro/SCF blocks. This was not needed before WordPress v6.7, but now it’s a must unless you make useless ugly 1 column ACF block layouts.
