<p>Headingo is a lightweight utility plugin that allows administrators to control which heading levels are available in the editor toolbar. This tool only works for websites using the Classic Editor.</p>
<p>These settings are applied to all users with editing permissions.</p>
<p>The configurable heading levels are:</p>
<ul>
<li>Heading 1</li>
<li>Heading 2</li>
<li>Heading 3</li>
<li>Heading 4</li>
<li>Heading 5</li>
<li>Heading 6</li>
<li>Preformatted</li>
</ul>
<p>This is especially useful for removing the Heading 1 (H1) option to prevent editors from mistakenly selecting it, as well as removing heading levels which are not required on your website.</p>
<p>This plugin is intended for websites that rely on the Classic Editor editing experience. It does not attempt to modify the Block Editor (Gutenberg), where heading availability is governed by editor and theme configuration (theme.json) by design. The Classic Editor plugin is required for this plugin to work (or a theme that allows you to switch to the Classic Editor without the plugin).</p>
<h3>Classic Editor</h3>
<p>The Classic Editor (TinyMCE) is fully supported. Selected heading levels and Preformatted can be hidden from the formatting dropdown while remaining available via keyboard shortcuts or pasted HTML. The Paragraph option is always available and cannot be toggled.</p>
<h3>Block Editor (Gutenberg)</h3>
<p>This plugin does not control heading levels in the Block Editor. Gutenberg does not currently provide a reliable API for plugins to override available heading levels, as these are controlled by editor and theme settings.</p>
