4WP FAQ is a smart wrapper around WordPress core Accordion blocks. It adds FAQPage JSON-LD, an optional aggregated FAQ registry, and usage context while keeping your front-end design intact.

<h4>Development</h4>
JavaScript and CSS are built with <code>@wordpress/scripts</code>. Human-readable source (<code>src/</code>, <code>webpack.config.js</code>, <code>package.json</code>) is in the public GitHub repository above — not in the distributed plugin ZIP.
From a clone of the repository:
<ol>
<li><code>cd</code> into the plugin directory</li>
<li><code>npm install</code></li>
<li><code>npm run build</code> — compiles block, admin, and setup apps into <code>build/</code></li>
</ol>
<h4>Key features</h4>
<ul>
<li>Wrap Accordion / Accordion Item (legacy Details supported)</li>
<li>FAQPage JSON-LD — site-wide toggle plus per-block override</li>
<li>Optional FAQ registry CPT with content scan and usage stats</li>
<li>Setup wizard for registry post type and taxonomy slugs</li>
<li>Convert to FAQ toolbar action on Accordion blocks</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Build FAQs with core Accordion blocks (or convert existing Accordion).</li>
<li>Click Convert to FAQ to wrap content in <code>forwp/faq</code>.</li>
<li>Enable JSON-LD in FAQ → Settings (recommended for SEO) or per block.</li>
<li>Optionally complete setup to aggregate questions into a registry list.</li>
</ol>
JSON-LD on the front end does not require the registry. The registry is for browsing, reuse tracking, and future features.

Adds custom field to the post & pages editor for custom JSON-ld schema markup also known as structured data. The plugin also validates if the JSON is formated correctly. <a href="http://coderisk.com/wp/plugin/websitescanner-custom-schema/RIPS-8iSfZmxGFd" rel="nofollow ugc"></a>
Add your own JSON-ld on every page, post and custom post without the <code><script></code> to show your own custom Schema markup.
Works well with the following plugins:
<ul>
<li><a href="https://wordpress.org/plugins/remove-schema/" title="Remove Schema WordPress plugin" rel="ugc">Remove Schema</a></li>
</ul>
Usecases:
With the combination of the WordPress plugin it’s easy to overwrite the schema on a specific page. 
If a plugin like Yoast SEO or other plugin or theme that generates schema you can disable the schema and add your own custom schema to the page.

Websitescanner Custom Schema

Adds custom field to the post & pages editor for custom JSON-ld schema markup also known as structured data.
