Why use an AJAX filterable post grid in Elementor?
Many basic grids reload the entire page when visitors switch categories. That feels slow—especially on mobile. With AJAX, only the grid content updates, making your site feel snappy and app-like.
✅ Key benefits
- Instant category filtering (no full page reload)
- Better mobile experience and faster interactions
- Higher engagement (users explore more posts/products)
- Lower bounce rate (smooth browsing)
- Great for blogs, news, portfolios, and WooCommerce
What you need before you start
- A WordPress website
- Elementor (Free or Pro)
- Flexi Post Grid installed and activated

Step-by-step: Create an AJAX filterable Elementor post grid
Add the Flexi Post Grid widget
Open your page in Elementor, search for Flexi Post Grid, and drag the widget onto the canvas. You’ll see a grid instantly, ready to customize.
Choose the post source
Select what you want to display:
- Blog posts
- Custom post types
- WooCommerce products
- Events (if you use event post types)
This matters because your filter options follow the taxonomy (categories/tags) for that post type.
Enable category filter (AJAX)
Turn on category filters and enable AJAX loading. Now when visitors click a category, the grid updates instantly—no page refresh.
Pick a layout that matches your website
Choose a preset layout (blog, news, portfolio, alternative styles) and adjust columns, spacing, typography, thumbnail size, and meta visibility. Clean spacing = better readability and click-through.
Pro tip: For best results, keep 2–3 columns on desktop, 2 on tablet, 1 on mobile for content-heavy grids.
Choose pagination mode (AJAX)
Select what fits your content style:
- Classic Pagination – structured navigation (great for SEO)
- Load More (AJAX) – great for blogs and galleries
- Infinite Scroll (AJAX) – best for feeds and news portals
Recommended: load 6–12 items per request for smooth performance.
Performance tips (so your AJAX grid stays fast)
Even the best grid can feel slow if the page is heavy. Use these proven optimizations:
- Compress images and use WebP where possible
- Enable caching (page + object cache)
- Limit posts per load (6–12 is ideal)
- Use a lightweight theme and avoid extra heavy scripts
- Lazy-load thumbnails (especially with infinite scroll)
SEO note: If you use infinite scroll, keep pagination/load more available too, so content remains discoverable and user-friendly.
