I’m not a developer. Can I still use FacetWP?

See our Getting Started screencast. If the video doesn’t make sense to you, then you’ll probably need to find a developer to assist you.

Do you offer custom development services?

We do not current offer paid implementation services. For custom development (site buildouts, design tweaks, other customizations) we recommend

Features and integrations

Does FacetWP work with my theme?

Probably. There’s tens of thousands of themes out there. If you tell us which theme, and we’ll try to figure out whether the theme is compatible.

Which page builders does FacetWP support?

FacetWP integrates with Bricks, Elementor and Beaver Builder.

FacetWP does not officially integrate with Divi, WP Bakery, or Oxygen Builder. Depending on your template setup you may get things to work, but these builders are not officially supported.

On these non-supported builders, you could always use FacetWP’s built-in Listing Builder to build your post listing. Or you could use Gutenberg blocks, or a custom WP_Query, or the WP archive page itself (if your post listing is an archive).

Does FacetWP integrate with WooCommerce?

Yes! FacetWP supports any plugin that uses post types to store products. WooCommerce, Easy Digital Downloads, and Jigoshop are all compatible.

One caveat: some page components (e.g. pagination and sorting) may need to be replaced with FacetWP facets for paging and sorting, although FacetWP has built-in support for WooCommerce’s default pagination and sorting.

Can I use FacetWP with WordPress blocks?

Yes, if you install the Blocks add-on, you can use facets alongside the following block types, in classic and block themes:

Source/Plugin Block name
WordPress WordPress Query Loop blockQuery Loop
WordPress Posts  List blockPosts List
WordPress Latest Posts blockLatest Posts
WooCommerce WooCommerce Products (Beta) blockProducts (Beta)
GenerateBlocks GenerateBlocks Query Loop blockQuery Loop
Kadence Blocks Kadence Posts blockPosts
Stackable Stackable Posts blockPosts
Spectra Spectra Post Grid blockPost Grid
Spectra Pro Spectra Loop Builder blockLoop Builder
Otter Blocks Otter Blocks Posts blockPosts

Consequently, with this add-on installed, you can also use FacetWP with these supported blocks in .html templates in block themes.

Can I use FacetWP to filter pages?

Yes, FacetWP supports listing and filtering of posts, pages, and any custom post type (as long as it is searchable).

Additionally, with a Professional license you can install the User Post Type add-on, which allows you to map users to a post type, and therefore filter users.

Can I use FacetWP to filter custom post types?

Yes, FacetWP supports listing and filtering of posts, pages, and any custom post type (as long as it is searchable).

Additionally, with a Professional license you can install the User Post Type add-on, which allows you to map users to a post type, and therefore filter users.

Can I use FacetWP to filter categories or terms?

No, FacetWP does not support filtering directly on categories or taxonomy terms, with one exception: product categories on WooCommerce shop- and product category archive pages.

But you can filter posts, pages, and posts of any custom post types by category or taxonomy term(s): by setting a taxonomy as a facet’s data source.

Besides posts, pages and custom post types, you can filter users, if you install the User Post Type add-on, which comes with a Professional license.

Can I use FacetWP to filter user listings?

Yes, Professional licenses include the User Post Type add-on, allowing you to map users to a post type, and therefore filter users.

Does FacetWP support WordPress multi-site?

Yes, FacetWP works well in a WordPress multi-site network setup. It can be activated in each sub-site individually, or you can use Network Activation (recommended). But be aware that each sub-site counts against your license’s site limit.

FacetWP will be able to filter content within each individual sub-site. It cannot filter or search across sub-sites, and there a no plans to support this in the future.

See this page for more info about using FacetWP with multi-site.

Installation, updates, license and account

How can I disable the admin notices to install add-on integrations?

Since version 4.1.8 FacetWP displays admin notices when you have certain plugins installed and the necessary integration add-ons are missing.

These notices were added because many users are unaware of the fact that some plugins do not work with FacetWP unless the related add-on is installed. For example, WPML needs the Multilingual add-on installed to work with FacetWP.

There are certain situations however in which you don’t need the integration add-ons. In these cases you can permanently disable these notices by adding the following code to your (child) theme’s functions.php:

How to use custom PHP code?

PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info

add_filter( 'facetwp_dismiss_notices', '__return_true' );
Do I get plugin updates?

Yes, automatic updates are enabled for sites with an active license key.

Why are automatic updates not appearing in my dashboard?

Make sure that you’ve activated your license (Settings > FacetWP > Settings). If you’re still not seeing updates, go to Dashboard > Updates, then click the Check again button. Sometimes WP’s update cache need to be flushed.

What happens when my license expires?

FacetWP will continue to work, but you will no longer receive plugin updates or support.

How much do renewals cost?

We offer a 20% renewal discount on the normal price.

Do staging sites count against the site limit?

Depending on your licence type, you can use your license up to 3 or 20 live sites.

You are also allowed to use it on as many local / dev / staging sites as needed.

You can see in your account which sites are considered as staging sites.

How can I get a (customized) invoice?
How to change the billing details on your invoice.
How to change the billing details on your invoice.

To generate and download your invoice, first log into your account.

If you want to customize the billing details on the invoice, don’t use an access token to log in. Log in with your username and password, because otherwise the “Update” button, as shown in the image on the right, will not be visible.

In your Purchase history, click the “View Invoice” link on the right of the purchase you want to generate an invoice for. This will take you to the invoice, which you can print or download as a PDF with the buttons at the bottom.

To customize the billing details, for example to add a company name, a billing address, or a tax/VAT number, click on the “Update” button in the “Invoice To” section, add your details, and click the “Save Billing Details & Generate Invoice” button.


Why do my facets disappear?

The most common cause of facets disappearing is because your facet shortcodes are inside of the facetwp-template container element. The element with that class will be dynamically replaced when using facets, so facets need to be outside of it to keep functioning properly.

In listings made with the Listing Builder, this issue will never happen, because the class will be automatically placed on the right element.

But if you are using a WP Archive or a custom WP_Query, or a setup with a page builder query/posts block for your listing, your facets may end up inside the element that has the facetwp-template class.

The solution in all cases is removing the facetwp-template class from where you placed it (if you did), and manually placing it on an element that (directly) surrounds the post loop.

For further explanations about the role of the facetwp-template class in FacetWP’s automatic query detection, and ways to fix issues with it, see the sections about it on the Using a WP Archive and Using a custom WP_Query pages.

Why is my facet empty?
  • Have you hit the Re-index button?
  • Does a valid listing template exist on your page?
  • Do you see a facetwp-template class on a container element surrounding your listing? If not, check the documentation on the listing template type you are using for ways to fix this. In most scenarios, you can add this class manually. If you are using an optimization plugin, check if you have an HTML minification setting enabled. HTML minification will remove FacetWP’s <!--fwp-loop--> HTML comment, which (on some listing template types) is used to automatically detect the listing and add the needed facetwp-template class. This happens most often using Cloudflare’s “Auto Minify” feature, and using Fast Velocity Minify.
  • Is your post type searchable? (is the exclude_from_search parameter set to false when the post type is registered)?
  • Does your facet show any rows after indexing? If not, there could be something wrong with the facet’s selected Data Source. Make sure that you select a valid data source and check if your posts have (valid) values saved for the selected field. After making corrections, re-index again to see the updated row counts. To check if facets are working okay in general, create a test facet with its Data Source set to “Post Type” and re-index. This is a Data Source that should always work.
  • For some specific types of custom fields — like serialized data or relationship fields — you may need to tell FacetWP’s indexer how to properly index the data.
  • Is your site hosted on WP Engine, and are your facets empty after filtering? Try disabling WPE_Governor, which is a WP Engine feature that limits long queries for performance reasons. WPE_Governor can also cause the indexer to stall or not index all your posts. See our WP Engine page for other WP Engine issues and solutions.
  • Are there any JavaScript errors in your browser’s Console that can be fixed or give a clue?
  • Turn on Debug Mode and make sure that FacetWP is using the right query.
  • Is the WordPress wp_footer() function present in your (child) theme’s footer section? The footer section is usually a file named footer.php. If this function is not there, FacetWP’s JavaScript and CSS assets cannot load in the footer, resulting in empty facets. Also code snippets using the “wp_footer” action will not work. If wp_footer(); is not present in your footer.php (or your main template, if it does not use a separate footer include), you can add it manually by adding <?php wp_footer(); ?> to the file, right before </body>. And of course, make sure footer.php is actually included in the template used, usually with WP’s get_footer() function.
  • Do you have post IDs higher than 4294967295 (2^32-1)? If so, your posts cannot be properly indexed because of the limitations of the database field that stores these post IDs. Implement this fix to increase this limit.
Why are my facets loading slowly?

FacetWP itself is very fast. It normally takes a fraction of a second to load results. However, every WordPress request (including AJAX) is only as fast as the slowest plugin.

The AJAX requests that FacetWP uses on pages with filters are ignored by most caching plugins, so the load time you’re seeing with FacetWP is your server’s and website’s true speed.

If FacetWP takes a while to load, there’s likely a larger underlying issue. Make sure to disable any unnecessary plugins, and ensure that your server has sufficient resources.

You can read more about the possible causes of slow filtering, and FacetWP’s speed and limitations when indexing, filtering and searching in our performance article, which also lists things you can do to speed up the filtering process itself.

If you want to increase the (true, uncached) loading speed of you pages, check out our tutorial about how to use Query Monitor to optimize performance by optimizing your database queries.

And see our guide on how to make your website load faster for an overview to get you started with increasing server and website performance.

We also have a free Caching add-on that caches FacetWP’s AJAX requests, which may help on high-traffic sites.

Why are my facets not working on mobile?

In the following scenario’s facets may not work correctly on mobile:

  • If you have a “Filter” link/button that opens a custom mobile sidebar containing your facets. If that link/button is set up as a link with a hash in its href, like this: <a href="#", when it is clicked, the # will be added the the page URL. This causes issues with FacetWP’s facet refresh, which uses URL variables. Be aware that some page builders automatically add a hash when creating a button or link element with an empty href attribute. To fix this, replace the # or empty href with java­script:;, like this:
<a href="javascript:;">Filter</a>
  • Note that you can also use FacetWP’s Mobile Flyout add-on to create a sidebar with facets.
  • If there are SSL issues. We’ve mostly seen this happen in IOS Safari. Often, users are testing a http:// URL, while the page is trying to connect to the https:// URL for the facet refresh. To fix this, make sure to force-redirect non-secure http:// URLs to secure https:// URLs. Most hosts have settings for this. You can also do this manually by adding a RewriteRule in your .htaccess file, or by using a plugin, like Really Simple SSL. If this is not the issue, try re-adding the SSL certificate for you domain.
  • If you have some sort of security or firewall app installed on your phone. Try deactivating these kinds of apps while testing.
Why am I seeing “FacetWP was unable to auto-detect the post listing”?

If you see this error, FacetWP can’t find a suitable query. This usually happens when you have a custom WP_Query on a standard WordPress page. To let FacetWP detect the custom query, you have to add facetwp => true to the query arguments. See this section for more information.

This error can also happen:

Or, if you are hosting your site on WP Engine:

Why do I see no results after using facets?

When there are no results in the listing (actually nothing, or a “no results” message) after using facets, but results do appear after a hard page reload, more often than not the issue is a malformed HTML structure of the page. This happens quite often, for example by accidentally copy-pasting a piece of code in the wrong spot.

On AJAX refresh, when using facets, FacetWP processes the HTML between the first opening <body> tag and the first closing </body> tag. When there are multiple opening or closing <body> tags on the page, or if they are missing, or in the wrong place, the processed content/template will not include the listing/results, causing the “no results” issue to happen.

So, if you see this issue, open the page source in your browser, copy the whole HTML into an editor, and check if your HTML structure is sound. Make sure all opening and closing <html></html>, <head></head> and <body></body> tags are present, in the right place, and appearing only once. Pay special attention to the opening <body> and closing </body> tags.

Why am I seeing duplicate results in my listing?

If you are seeing duplicate posts in your listing, especially in combination with a Pager/Load more facet or Sort facet, the cause is almost always the way the posts are ordered in the query, which is determined by the orderby query argument.

If results are ordered by a value that is the same (or empty) for multiple posts, or by a random value, MySQL does not have a fallback and will often sort erratically.

In this tutorial you can read which scenarios can cause this, and how to fix it quickly by adding a secondary, fallback sort order to the listing query.

Why are not all my posts appearing in my listing?

Posts missing from your listing template on first page load (before using any facets) can be caused by several reasons.

First, make sure you are not unintentionally filtering the query (for example by category or a custom field). The way you could be doing that depends on the type of listing template you are using. For example, when using a custom WP_Query, you could be setting a meta_query argument, or you could be using a pre_get_posts hook. When you are using the Listing Builder, you could be using query filtering rules, or the facetwp_query_args hook.

Next, check if you are ordering the query by one or more custom fields that do not exist for certain posts. If this is the case, you need to either make sure the field exists for all posts (usually by saving them), or adapt the meta_query to account for both the existing and the non-existing custom field(s).

Why do I see more posts than my “post per page”?

If you see more posts in your listing than you have set in your listing query’s posts_per_page argument (or setting), check if you are using sticky posts.

See our sticky posts tutorial for workarounds you can implement to ignore sticky posts in FacetWP listings entirely or partially, and how to make them work if you actually want them.

Another reason could be that your listing is using the wrong query. First, try enabling the “Strict query detection” setting. If that does not help see this page about using the right query and the Troubleshooting page for more info.

Why is my layout different or are images missing after filtering?

Some plugins and themes use JavaScript to modify the layout, load images, or apply animation effects. Some examples include masonry or isotope layouts/grids, image lazy loading, and sliders/carousels.

These scripts run on the initial page load, but do not usually run after each FacetWP AJAX refresh, meaning that they’ll likely need to be manually re-triggered within a facetwp-loaded event.

Some theme and plugins offer a setting that (re-)triggers these scripts on AJAX refresh.

Why is my page scrolling?

Since version 4.2.12, FacetWP has a Scroll target setting to enable page scrolling when using a Pager facet. Except in this Pager facet setting, FacetWP and its add-ons do not add any scrolling behavior anywhere.

If you see unwanted scrolling behavior, check your theme settings and other plugins.

Make sure you are not using a custom scrolling solution from our scrolling tutorial in your (child) theme’s functions.php or a code snippets plugin.

If you are using the Beaver Builder add-on, check if you have Beaver Builder’s “Render CSS/JS assets inline” setting enabled, or if you are using the fl_builder_render_assets_inline filter hook, which both cause a JavaScript error that re-enables Beaver Builder’s page scroll that is prevented by FacetWP’s Beaver Builder add-on.

Why isn’t FacetWP working with my caching plugin?

If you’re using a caching plugin, in general, make sure that HTML minification and script deferring are disabled.

FacetWP has built-in support for WP Rocket.

Also, see our tips and tricks for using Cloudflare, Fast Velocity Minify, and WP Engine.

What should I do if indexing stalls?

FacetWP’s indexer can stall temporarily, for several reasons. If this happens, the first thing to do is wait a few minutes. FacetWP includes built-in resume functionality. It should resume automatically after a minute or two, if you keep the FacetWP settings screen open.

In specific circumstances, the indexer can get permanently stuck, often around the same percentage. These are the most common causes:

Why are my value modifiers not working?

Value modifiers need to be entered like this:

How to enter value modifiers correctly: use the exact labels with capitals and spaces, each on one line, without commas.
How to enter value modifiers correctly: use the exact labels with capitals and spaces, each on one line, without commas.

The following things often go wrong:

The values you enter in a facet’s “Value modifiers” field each need to be on a separate line in the form field. Do not put them on one line with commas or add commas to each line.

The values need to match the label (not the slug) of the value exactly, including spaces and capitalization. For example, if you have a category called “Fall Collection”, the value entered in the “Value modifiers” field needs to be exactly that: Fall Collection.

If you have not modified the facet values with output hooks like facetwp_facet_display_value, the quickest way to determine the labels is to look at the facet value labels themselves: the labels beside the checkbox or radio button, or the options in the dropdown. Also make sure to check if capitalization is not changed with CSS, for example with text-transform: lowercase.

In hierarchical facets, if you use “Show only these values”, if you want only specific child terms to show up, you need to include their parent terms (on all levels) too. Or you need to set their parent term ID in the “Parent term” setting. If you use “Exclude these values”, you can directly exclude child terms, without excluding their parent terms.

Why is my Sort facet not working on my products/shop page?
The only two WooCommerce's 'Default product sorting' options that work with Sort facets.
The only two WooCommerce’s “Default product sorting” options that work with Sort facets.

If you are using WooCommerce, and your Sort facet does not work on your products/shop page, you probably have set WooCommerce’s “Default product sorting” setting to a sort option that is incompatible with Sort facets.

There are only two “Default product sorting” options that work with Sort facets:

  1. Default sorting (custom ordering + name)
  2. Sort by most recent

The other sort options are incompatible because FacetWP cannot change them.

For more info and ways to still use one of the incompatible sort options, see this section on the WooCommerce page.

Why are my Listable / Listify homepage facets and submit button not working?

The Listable and Listify themes both have FacetWP integration that, at the time of writing, is incompatible with FacetWP 3.9.x.

Listable and Listify are using deprecated FacetWP functions, causing facets and the submit button on the homepage to malfunction.

How to hide empty facets?

See this explanation on how to hide empty facets.

How to hide facet counts?

How to hide the counts depends on the facet type and how general or specific you want to target facets to hide the counts for.

Facets with a dropdown UI type need a different approach than facets with checkboxes or radios. Some facets can have different UI types, so the method varies.

How to hide counts for facets of type:

Can I use multiple queries / FacetWP templates on the same page?

No, FacetWP was intentionally built to support only one filterable listing per page.

Adding support for multiple filterable listings would greatly increase the complexity of the core plugin, which we are not interested in doing. Adding this is currently not on the roadmap.

Using any of the supported listing template types, you can put multiple listings on a page, but only one can be enabled for FacetWP.

Note that if you are using the Listing Builder, you can add more than one listing shortcodes to the same page. Each listing template can have its own grid layout, styling, and query. But still, only one of them can be “dynamic” and will react to the facets on the page. The others must be “static” listing templates that will not react to facets.

If you are using the Elementor add-on, the same applies: you should place only one filterable Elementor FacetWP listing widget on the page. Other, static listings can be used, but they will not be filterable. Static listings can be placed with a Shortcode widget.

Does FacetWP support infinite scroll?

No, FacetWP does not support infinite scroll, which is intentional.

Plugins that add any form of infinity load / infinite scroll will not work as expected.

The closest thing is the Pager facet, which has a pager type that generates a “load more” button, working similar to infinite scroll.

How fast is FacetWP?

FacetWP was built with performance in mind and is very fast itself. We’ve structured and highly optimized our data storage and have analyzed every query to make sure that it runs as efficiently as possible.

So ultimately, FacetWP’s speed depends on your server, the theme setup, your plugins, and the amount of content. If your server is overloaded (i.e. too many heavy plugins or other users) or underpowered (too little memory or CPU power), then obviously FacetWP will not run at its peak.

See our guide on how to make your website load faster for an overview to get you started with increasing server and website performance.

Factors that determine the speed of filtering itself:

You can read more about each of these factors in our performance article, which also describes the possible causes of slow filtering, and FacetWP’s speed and limitations when indexing, filtering and searching.

If you want to increase the (true, uncached) loading speed of your pages with facets, check out our tutorial about how to use Query Monitor to optimize performance by optimizing your database queries.

We also have a free Caching add-on that caches FacetWP’s AJAX requests, which may help on high-traffic sites.

What are FacetWP’s limits and scalability?

Check out our performance article about FacetWP’s speed, limits and scalability when indexing, filtering and searching.

Does FacetWP support pretty permalinks?

We are occasionally asked whether FacetWP supports pretty URLs, e.g. /make/audi/model/a4/ instead of ?_make=audi&_model=a4.

FacetWP only supports GET-based permalinks. “Pretty” permalinks quickly lose their appeal as more selections are made. Plus it may actually be bad for SEO, since search engines would see many different URLs with the same content.

That’s probably why most large eCommerce sites stick with GET-based permalinks.

For more info about FacetWP’s URL, see this page.

Why does FacetWP prefix its URL vars?

FacetWP’s query variables use a _ prefix to prevent conflicts with WordPress and other plugins.

WordPress has many reserved terms and reserved query variables. Unexpected things would happen if FacetWP would use them.

For more info about FacetWP’s URL variables, see this page.

How to track pageviews with Google Analytics?

This page explains how to track pageviews of facet pages with Google Analytics 4.

Can I use “OR” logic between facets?

No, when using multiple facets, they are always compared using “AND” logic. FacetWP is designed to “filter down” in the results.

Using “OR” logic is possible for individual facets. If you are using a Checkboxes facet or an fSelect facet, you can use “OR” logic by setting the “Facet logic” setting.

Can I show facet choices with no results?

A frequently asked question is if it is possible to show all facet choices (for example all terms in a taxonomy), also if there are no results for some of those choices.

The answer is no; FacetWP only indexes and displays facet choices that have results.

Note that some facet types (like Checkboxes, Radio and fSelect) have a “Show ghosts” setting, which will show “ghost” (dimmed) choices if there are no results for them. But the same applies for these ghost choices: they need to appear in the unfiltered results, and can only become ghosts after being filtered out. If a facet choice has no associated posts, then it will never appear.

How to automatically scroll the page on facet interaction?

An often-asked question is how to automatically scroll the page to the results (or to the top of the page, or another target) when using facets, a specific face (type), or even a specific facet choice.

Our page scrolling tutorial shows a wide range of examples that should cover most scrolling scenarios.

Pagination scrolling can be enabled with the Pager facet’s scroll target setting (available since FacetWP 4.2.12).

How to add a loading spinner or fade the results during facet refresh?

This tutorial explains how to add a loading text or spinner icon to the listing template during facet refresh.

You can also fade the listing template during refresh, or hide it until facets are selected.

How to add a Map facet to single posts or pages?

We often get the question if it is possible to use the Map add-on to show a map on a single page, post, or custom post type post. A use case would be to show the location of a store, hotel, restaurant, or event.

This is possible, and actually not very complicated. Just follow the steps described in this tutorial.

Is there a button, tab, or toggle/switch facet type?

No, but most facet types can easily be styled to your liking, as long as their functionality works for your use case. They consist of simple HTML, like nested <div> and <span> elements. Even the ones that look like they use real HTML form elements, for example, the Checkboxes and Radio facet types, use simple CSS background images for their icons.

Some styling examples:

Can I use the offset query argument with FacetWP?

No, not directly. FacetWP does not work with a directly set offset query argument.

See our offset tutorial for an explanation of the issues, and an alternative solution that lets you use offset indirectly.
