Sectioneer adds a curated, theme-aware page-building experience to the WordPress 
block editor — a section library, one-click insert, and optional AI section 
generation and editing. It is built entirely on WordPress’s public extension 
points (SlotFills, block filters, the command palette, the Abilities API and the 
WordPress AI Client), so it installs as an ordinary plugin and keeps working across 
core upgrades. It never forks core or replaces the editor.
Open any page or post (or the Site Editor), click the Sectioneer icon in the 
top-right toolbar, and the Sections panel appears.
<h4>Features</h4>
<ul>
<li>Section library — ready-made sections (hero, features, call to action, and 
more) with search and one-click insert.</li>
<li>Theme-aware insert — inserted sections adopt the active theme: raw colors are 
remapped to the nearest theme.json palette token, so sections never look “pasted in”.</li>
<li>AI section generation (optional) — describe a section in plain language and 
Sectioneer generates valid block markup for it, seeded with your theme’s design 
tokens. Select a block first to revise it in place instead of inserting a new one.</li>
<li>Safe by construction — all inserted markup (curated or AI-generated) is parsed 
and rebuilt against registered block types; unregistered or unsafe blocks are dropped.</li>
<li>One consistent home — every feature lives in a single Sectioneer editor sidebar, 
in both the post editor and the Site Editor, with a first-run guide so it’s easy to find.</li>
</ul>
The curated section library works on its own. AI generation is an optional 
enhancement that degrades gracefully when no AI provider is configured.
<h4>AI section generation and external services</h4>
Sectioneer does not bundle any AI provider, contain any API keys, or make any 
external requests on its own. It registers a WordPress Ability and calls it through 
the WordPress AI Client; the underlying provider is resolved on your own site.
To enable AI generation you install and configure a separate WordPress AI provider 
plugin (for example AI Provider for Google, AI Provider for OpenAI, or AI 
Provider for Anthropic) and supply that provider’s API key. When — and only when — 
you click “Generate”/”Update”, your prompt text and the slugs of your active theme’s 
design tokens (color and font-size names) are sent to whichever AI provider you 
configured, via the AI Client running on your site, and the generated block markup is 
returned. That request is governed by the terms and privacy policy of the AI provider 
you chose. If no provider is configured, Sectioneer shows a notice and the AI controls 
are disabled — nothing is sent anywhere.

An extensible page-building layer for the block editor: curated, theme-aware sections with optional AI generation, inside Gutenberg and FSE.

Settings provide many different ways to Select which Theme should appear where on your WordPress web site:
<ul>
<li>Just for Site Home</li>
<li>By URL (Version 5 adds support for Query keyword=value as part of a unique URL);</li>
<li>By Prefix URL, matching all URLs that begin with the same characters (“Prefix URL”);</li>
<li>By Wildcard Prefix URL with one or more Asterisks (“*”) representing arbritrary subdirectories in the URL;</li>
<li>By Query Keyword found in any URL, not matter what the Value;</li>
<li>By Query keyword=value found in any URL;</li>
<li>By Sticky Query keyword=value that sets the Theme for a given Visitor until an Override Query keyword=value is found in a future URL (Advanced Setting requiring the Visitor’s browser to accept Cookies; incompatible with certain plugins that block Cookies);</li>
<li>Everywhere (Advanced Setting that overrides the WordPress Active Theme);</li>
<li>All Pages (Advanced Setting that works with most, but not all, Themes and Plugins);</li>
<li>All Posts (Advanced Setting that works with most, but not all, Themes and Plugins).</li>
</ul>
None of the Themes in the WordPress Theme Directory alter the appearance of the WordPress Admin panels. As a result, this plugin does not allow Theme Selection entries to specify URLs for WordPress Admin panels.
Use with Paid Themes: On-going full scale testing of Themes by this plugin’s author is only possible if the Theme is found in the WordPress Theme Directory. Although (Version 5 of) this plugin should now work with all Themes, any problems encountered while using Paid Themes will be difficult to diagnose. As described in the FAQ tab, a WordPress Network (Multisite) is an alternative to this plugin, as a way to create a single web site with more than one Theme.
A similar situation exists with Paid Plugins.
Use with Plugins that Cache: You may find that you have to flush the Cache whenever you change Settings in the jonradio Multiple Themes plugin. Some Caching plugins only cache for visitors who are not logged in as users, so be sure to log out before testing the results of your jonradio Multiple Themes settings.
Changing Theme Options (Widgets, Sidebars, Menus, Templates, Background, Header, etc.)?: After installing and activating the plugin, see the plugin’s Settings page and click on the Theme Options tab for important information on changing Options for Themes other than the Active Theme.
How it Works: The plugin does not change the Active Theme defined to WordPress in the Appearances-Themes Admin panel. Instead, it dynamically (and selectively) overrides that setting. Which means that simply deactivating (or deleting) this plugin will restore the way that Themes were displayed prior to installing this plugin. However, in some situations, it is possible to inadvertently alter Theme Options for the Active Theme when using either of the Methods described on the plugin’s Setting page Theme Options tab.

Special thanks to Jon ‘jonradio’ Pearkins for creating the plugin and making adoption possible.

Multiple Themes

The plugin doesn't seem to work. And the support requires you to register to add a ticket, not useful.

Doesn't seem to work


I didn't expect it to work with wp 6.7.1 and both combination of classic theme and FSE theme. But it works! This was such a pleasant surprise! Excellent idea and realization. I would only suggest that settings interface of a plugin is a little more straightforward. Also, including regex for URL matching would be nice as well.Message to the plugin author - you can update compatibility to match WP 6.7


Fabulous!

Select different Themes for one or more WordPress Pages, Posts or other non-Admin pages.  Or Site Home.
