This plugin will disable the Core Block Patterns, included with WordPress 5.5 (and higher versions). Even if your theme enables them, this plugin will overrule your theme and disable Core Block Patterns. It will not disable any custom or plugin Block Patterns. The plugin has no settings and should work in WordPress MU as well as single WordPress installations.

Disable Core Block Patterns

This plugin will disable the Core Block Patterns, included with WordPress 5.5 (and higher versions).

Pattern Wrangler makes managing WordPress block patterns easy, and is designed for both hybrid classic/block themes, block themes, and is compatible with most page builders through its shortcode support. Pattern Wrangler allows you to curate the pattern experience for your clients, controlling down to the pattern what the client sees in the block editor.
Here are the major features:
<ul>
<li>New Patterns Screen – A new Patterns screen now shows at a glance all of the patterns available for your site. You can sort through both local and registered patterns, and selectively disable or enable whatever patterns you’d like your client to see. A real-time preview is available by clicking on the pattern. </li>
<li>Hide All Patterns – Completely hide patterns from the block editor in one click. This also hides the Patterns menu item.</li>
<li>Selective Hiding – Hide core, remote, theme, or plugin patterns while keeping your custom patterns visible. You can also hide synced and unsynced patterns together or separately. If you need to hide WooCommerce patterns, you can do so by hiding all plugin patterns, or using the Patterns View to disable the patterns individually.</li>
<li>Category Management – Disable, map, and rename registered categories from themes and plugins for better organization. This will help you keep local and registered patterns organized together. For example, you’d like to create a “Call to Action” category for a local pattern, but a registered category already exists, do you have a duplicate in the patterns view. In this case, map the registered category to the local one and remove the duplicate.</li>
<li>Output Patterns Anywhere – Use a shortcode or PHP function to display local patterns in page builders, widgets, your theme, or in other blocks. This works well in Multisite and allows you to use synced patterns across the network.</li>
<li>Pattern Preview – Preview a pattern on the frontend with shortcuts in the block editor.</li>
<li>Cross-Site Pattern Copying – Transfer patterns, including the remote images, between WordPress sites effortlessly. This is useful if you’re copying a pattern from one site to another or copying a pattern from a production site to a development site.</li>
</ul>
Available features on the Patterns screen include:
<ul>
<li>Sort between Local and Registered patterns.</li>
<li>Filter between categories and pattern source.</li>
<li>Click a pattern to view a real-time preview in a lightbox.</li>
<li>Copy registered patterns to a local copy.</li>
<li>Export all patterns to JSON.</li>
<li>Copy a pattern to the clipboard.</li>
<li>Disable each pattern individually.</li>
<li>Quickly edit local patterns.</li>
<li>Add new patterns or import patterns from JSON.</li>
</ul>

<h3>Requirements and Compatibility</h3>
Requires WordPress 6.8 or higher. 6.9 is recommended.
Fully compatible with most themes, including block themes. Ideal for hybrid setups and page builders. If you need to use a block in a page builder or classic editor, you can create a new pattern, configure the block, and use the built-in shortcode. If you need to use the pattern in a template, you can use the built-in PHP function, which is available for all local patterns.
This plugin has been tested almost exclusively with <a href="https://wordpress.org/themes/ollie/" rel="ugc">the Ollie theme</a>, which is a phenomenal block theme. All the 202x themes have also been tested, as well as Blocksy, Astra, and GeneratePress.
If you have any issues with the previews, please be patient in your support requests, and also specific as to which themes or plugins may be involved.
❤️ Please help spread the word about this plugin through your kind review.
