PDF Gallery Viewer allows you to easily embed PDF galleries with live previews. It uses PDF.js to render the first page of each PDF directly in the browser, without relying on server-side libraries like Imagick. Each item includes a customizable title and a “View” button that opens the PDF in a modal viewer.
The layout is responsive and adapts from a multi-column grid to a single-column stack on smaller screens.
Key Features:
<ul>
<li>Live thumbnail of first PDF page (via PDF.js)</li>
<li>Responsive layouts (Grid, List, or Slider)</li>
<li>Modal viewer with zoom, navigation, and download</li>
<li>Gutenberg block with layout selector and drag-and-drop file integration</li>
<li>Tooltip + truncation for long titles</li>
<li>Dynamic shortcode generation by category, tag, or post</li>
<li>Sorting UI (Title / Filename / Manual drag & drop)</li>
<li>Manual ordering with FIFO/LIFO behavior for newly added items</li>
</ul>
<h3>Usage</h3>
Basic usage:
[pdf_gallery url=”https://example.com/doc.pdf” title=”Document Title”]
Multiple items in a container:
[pdf_gallery_container layout=”grid”] 
[pdf_gallery url=”…” title=”…”] 
[pdf_gallery url=”…” title=”…”] 
[/pdf_gallery_container]
Sorting / ordering:
[pdf_gallery_container layout=”grid” order_by=”title” order=”asc” ui=”1″] 
… 
[/pdf_gallery_container]
Manual ordering (UI drag & drop) with FIFO/LIFO for newly added items:
[pdf_gallery_container id=”my-gallery” layout=”grid” order_by=”manual” manual_mode=”fifo” ui=”1″] 
… 
[/pdf_gallery_container]
IMPORTANT: Manual ordering is managed by admins and saved server-side (post meta) so the order is the same for all visitors. 
For reliable persistence, always set a stable id=”…” on each container (the Gutenberg block does this automatically).
Dynamic by category:
[pdf_gallery_container category=”brochures” layout=”slider”]

Boxzilla is a WordPress popup builder for adding targeted popups, slide-ins, and call-to-action boxes to your site. Show a box after a visitor scrolls, waits on the page, views multiple pages, clicks a link, or reaches a specific page element. Each box can contain any WordPress content, including shortcodes from form plugins.
Use Boxzilla for newsletter sign-up forms, content upgrades, product offers, important notices, surveys, or any other message that should appear at the right moment without taking over the whole page.
<h3>What you can build with Boxzilla</h3>
<ul>
<li>Targeted WordPress popups – show boxes only on the posts, pages, or conditions you choose.</li>
<li>Scroll-triggered slide-ins – open a box after a visitor scrolls past a percentage of the page or reaches a specific element.</li>
<li>Timed call-to-action boxes – show a message after a set number of seconds on the page.</li>
<li>Pageview-based prompts – wait until a visitor has viewed several pages before showing a box.</li>
<li>Click-triggered modals – open a box from a link, button, or URL hash such as <code>#boxzilla-94</code>.</li>
<li>Flexible content – add text, images, forms, shortcodes, embeds, or custom HTML to any box.</li>
<li>Visual appearance controls – choose the position, animation, colors, and box style from the WordPress admin.</li>
<li>Dismissal control – decide how long a box should stay hidden after a visitor closes it.</li>
<li>Small front-end script – Boxzilla adds only 6 kB of JavaScript to your website.</li>
</ul>
<h3>Works with your forms and content</h3>
Boxzilla works with plugins that output shortcodes, including <a href="https://wordpress.org/plugins/mailchimp-for-wp/" rel="ugc">Mailchimp for WordPress</a>. Add the shortcode to your box content, choose when the box should appear, and publish it.
<h3>Premium add-ons</h3>
The core Boxzilla plugin is free. Paid add-ons are available for advanced triggers and integrations, including exit-intent popups and time-on-site targeting.
