<h4>Creating Portal</h4>
This plugin will provide…
<ul>
<li>Custom post type with single page and archive page.</li>
<li>Custom taxonomy associated to CPT.</li>
<li>Incremental search box.</li>
<li>AI Overview(Since 2.0.0)</li>
</ul>
<h4>AI Overview</h4>
AI Overview answers user questions based on your FAQ content using a large language model. 
It uses <a href="https://packagist.org/packages/wordpress/wp-ai-client" rel="nofollow ugc">wp-ai-client</a> (experimental) bundled via Composer, which requires an AI service to be configured in WordPress. Since wp-ai-client is still experimental, its API may change in future releases.
You can configure AI behavior and rate limiting from Settings > Hamelp in the admin panel.
Using the Block
Add the AI FAQ Overview block in the block editor. The block has the following options:
<ul>
<li>Placeholder — Input placeholder text.</li>
<li>Button Text — Submit button label.</li>
<li>
Show Sources — Display related FAQ links below the answer.
Using the Template Function
</li>
</ul>
You can also use <code>hamelp_render_ai_overview()</code> in your theme templates:
<pre>
<?php echo hamelp_render_ai_overview(); ?>
</pre>
The function accepts an optional array of arguments:
<pre>
<php
echo hamelp_render_ai_overview( [
 'placeholder' => 'Ask a question...',
 'button_text' => 'Ask AI',
 'show_sources' => true,
] );
?>
</pre>
The function automatically enqueues the required JavaScript and CSS assets.
<h4>Search Box</h4>
You can use shortcode <code>hamelp-search</code> in page content.
<pre>
[hamelp-search label='Enter your question here.'][/hamelp-search]
</pre>
And you can call in your theme altenatively.
<pre>
<?php echo do_shortcode( '[hamelp-search][/hamelp-search]' ) ?>
</pre>

This plugin will allow creation of admin help tabs (and associated sidebars) on any screen in the WordPress admin area. It creates a custom post type called Help Tabs to store information. You need to add the following info to make it work:
<ol>
<li>Title – The title of your tab</li>
<li>Main content area </li>
<li>Screen – What page/screen it should appear on</li>
<li>Type – Help tab or tab sidebar</li>
</ol>
HELP TAB EXAMPLE: 
Let’s say I want to add a help tab on the main Help Tabs listing page that says something about my plugin. I would use:
<ol>
<li>“My Main Tab”</li>
<li>“This is a main tab with my own info on it!”</li>
<li>“edit-sbah_helptab”</li>
<li>Select “Tab” (the default)</li>
</ol>
HELP SIDEBAR EXAMPLE: 
Let’s say I want to add a help sidebar (these are the areas to the right with extra info and links) on the main Help Tabs listing page. I would use:
<ol>
<li>“My Sidebar”</li>
<li>“This is a sidebar!”</li>
<li>“edit-sbah_helptab”</li>
<li>Select “Sidebar”</li>
</ol>
IMPORTANT NOTE: While there can be multiple tabs per page, there can be only ONE sidebar per page. If you add others to the same page, only the first one found will show.
NOTE: I also have a plugin that does Admin Pointers (those blue info boxes), if you are interested in that one you can find it here: https://wordpress.org/plugins/better-admin-pointers/
This plugin leverages the great work done by others here:
