Yes, there is a hook called wpc_hierarchy_opened>

apply_filters( 'wpc_hierarchy_opened', [] );

You can use this hook to write custom logic that fits your needs for opening hierarchy elements by default.

Hi Victor,

Thanks again for helping me fix the previous issue with the shop page and filters.

Now I’m trying to adjust how the hierarchy behaves in the filters. I’d like all child terms to be opened by default (not collapsed) when the page loads, while keeping “Show Hierarchy” enabled in the filter settings.

You mentioned that I can use the wpc_hierarchy_opened hook: apply_filters( ‘wpc_hierarchy_opened’, [] );

I tried to add some custom code via a snippet plugin, but it didn’t change anything – most likely because I don’t know the exact parameters and expected return value of this hook.

Could you please send me a working example of PHP code that:

Opens all terms in a hierarchical filter by default, for a filter based on Product Categories (taxonomy: product_cat).

Shows how many arguments wpc_hierarchy_opened receives (e.g. $opened, $args or similar) and what type/format it expects to be returned.

With an example snippet I can then adapt it to my own logic.

Thank you in advance!

Hi jinchenjia19

Here is the ID on the front of the required filter: https://prnt.sc/FQ5xvz115vcS

And this is an example of a code:

add_filter( 'wpc_hierarchy_opened', 'my_opened_terms' );
function my_opened_terms( $terms ) {
    return [ 3043 ];
}

Best Regards,
Victor

Thank you – look forward to an update.

Hi web-maverick

About the issue with the search field hiding in the mobile, try to add the following CSS in the Filters > Settings > Experimental > Custom CSS:

.select2-container--default .wpc-filter-everything-dropdown .select2-search--dropdown.select2-search--hide {
    display: block;
}

Best Regards,

Thank you, this has solved the issue!

Hi Felix0314

We have chosen “Pages + Shop page” in the filter set and the filters appeared; however, you need to display the products on that shop page in order to filter them. Currently, that page is empty.

Best Regards,
Victor

Hi Victor, currently on the Shop page, I’m using Elementor’s Loop grid, and the selected query are as attached https://postimg.cc/rDLY5KWD. The query are exact the same as previously when it is working, but in the filter settings is can’t locate the product queries.

We are not sure how exactly it is configured in Elementor, but where exactly are the products on your shop page: https://prnt.sc/7nM8c-ChvSM3

Perhaps we are missing something, but we don’t see any products on the page.

Hi ravi000

You can try to turn off the permalinks in the plugin so the filters will use GET parameters. For that, you can use the following code:

define( 'FLRT_PERMALINKS_ENABLED', false );

Also, you can add any solutions on the server side, such as:
1) Use a Firewall/WAF to block or rate-limit bad user agents and IP ranges.
2) Improve robots.txt and server rules to drop unwanted bot requests at the server level.
3) Use bot-protection plugins to automatically block suspicious crawlers.
4) Set rate limits per IP in Cloudflare, Nginx, or Apache.
5) Use CAPTCHA for unknown bots and heavy endpoints.
6) Monitor access logs to identify abusive IPs or user agents and block them permanently.

Hi joneyquest

Thank you for choosing Filter Everything PRO.

At the moment, you can create a price range slider. To do this, you need to create a Custom Field Numeric filter and use the meta key _price if this is for WooCommerce. If it’s for any other CPT, you need to use your own price meta key.

The ability to create prices like:
1-5$
5-10$
10-15$

Only in development, and most likely, it will be included in the 1.9.3 update.

Hi pajeromasterau

Can you please send the credentials to the wp-admin dashboard following this document. So we can create an example of filters for you. You can also attach the link to the page where you want the filter to be and specify exactly what you want it to filter on that page.

This way, we could create an example of such filters for you.

Best Regards,
Victor

Hi pajeromasterau

We have checked the site, and we didn’t find any product attributes; they basically have no terms in them. So we simply added a category filter as a secondary one after the model filter, as a child filter of a tag filter. You can add any other attribute as a third one (or as many as you need) and make them child filters of the previous one to create such a chain.

Victor

Hey, we have purchased your license with paypal. You can check Web Visuality in your website.

We have checked the site and how it is set up, and placed the filter set on this exact page.

Since you have WPML and most likely want to apply filters in different languages, please check this page: https://filtereverything.pro/resources/with-wpml-polylang/

Hi ali34121

Currently, the development team, together with SEO experts, is actively working on improving how the plugin handles this, such as removing links from filter terms, limiting the maximum number of selectable filters at once, and similar solutions. This is currently under active discussion to find the best approach.

What you can do on your side is use firewall settings or .htaccess rules with wildcards to prevent crawlers from going further on filtered pages. They would only have access to the main pages, like site.com/shop/, while anything after /shop/ that represents filters would be blocked.

You can also try to turn off the permalinks in the plugin so the filters will use GET parameters. For that, you can use the following code:

define( 'FLRT_PERMALINKS_ENABLED', false );

If you have any suggestions regarding what can be done on the plugin side to address this matter, please let us know.

Best Regards,
Victor

Hi pajeromasterau

Absolutely yes.

1) The first filter is a brand filter, which can be created in the Brands taxonomy or as an attribute, whichever you prefer.

2) The second filter is an attribute called Model with all the required terms.

3) The third filter is another attribute, like Modification or anything else you need. You can then create a child-parent filter structure if required in the filter set.

But first things first: you need all the brands in one taxonomy, and the rest in separate attributes. Do you already have this set up on your site?

Best Regards,
Victor

Hi jpsquared

No, this is not weird at all. When it comes to programming, anything can happen. Maybe some conflicting prefixes for filters with existing plugins reserved slugs for those plugin pages, and so on.

Can you please send the credentials to the wp-admin dashboard following this document so we can check it?

Also, please provide the link to the exact page that shows a 404 error when our plugin is turned on, so we can test that specific page.

Best Regards,
Victor

Hi mesarcovaeduco

Thank you for choosing Filter Everything PRO.

In general, within one filter set, you can create only one filter from the same entity. For example, if you create a filter from the taxonomy “Product category,” you cannot create any other filters from the same taxonomy in that same filter set.

However, you can create multiple filter sets and apply them on the same page, using the same number of filter widgets or shortcodes to display them all. In each filter set, you can modify the Product Category filter from the More Options section to use include/exclude settings to define the exact filter terms you want to display.

it seem that this most simple thing cant be done??

To be fair, this is not the “most simple thing.” This is exactly why WooCommerce has product attributes, so you don’t have to rely on a single product category taxonomy and try to divide it into unrelated groups to use on products instead of attributes.

In an ideal setup, these things should be separated: product categories should contain general categories such as laptops, microwaves, smartphones, TVs, while attributes (or another custom taxonomy) should contain specific properties for those products. For example, a skin type attribute with the terms normal, sensitive, dry, mixed, or a RAM attribute with the terms 1GB, 2GB, 4GB, 12GB, and so on. This way, you can create a dedicated filter for each attribute, responsible only for RAM, skin types, color, and other specific properties.

Example of a category structure:
Skin-care and personal-care products (main)
— Facial Skincare Products
— Body Care Products
— Sun Protection
— Makeup

After we choose the required category, for example, “Body Care Products,” the next filters should be from any separate attribute related to those products. Example of such attributes and terms that they contain:

skin_type: normal, dry, oily, mixed, sensitive
skin_concern: acne, redness, dryness, wrinkles
fragrance: fragrance-free, light fragrance, strong fragrance
use_time: day, night, day & night

The RankMath plugin is quite popular. That’s why I felt the need to tell you.

Yes, I tested all the plugins one by one. The RankMath plugin caused the problem.

I reinstalled the previous version of this plugin and the problem was fixed.

When I checked my website just now, I noticed that RankMath had released version 1.0.259.1

I updated this version on my website. All issues have been resolved.

However, I think it would be beneficial for you to discuss this situation with them.

Yes, indeed, the RankMath plugin is quite popular. Thank you for all of the information; that is great news that everything is back to work. We will pass it on to the development team so they can do the required contacts.

Hi ashwiniprabhu14

Thank you for choosing Filter Everything PRO.

Please send the credentials to the wp-admin dashboard following this document so we can check it.

After you send the credentials, we will start from the first request, which is the issue of filters not displaying on the search pages. To check this issue, please attach the link to the exact search page where you want the filters to be displayed so we can examine it.

Please write one request at a time. When we make sure that it is absolutely resolved, we can move to the next one, and so on. Do not send a list of multiple requests at once because it is not efficient to provide support for all of them simultaneously; it will only cause more confusion instead of actually providing the information needed for each request.

Best Regards,
Victor

Hello, thank you for your response.

I have submitted the credentials via the method in the document. Yes, we can start with ISSUE # 1 and keep other issues separate till this is resolved.. Please do let me know if I should proceed with other issues in this thread itself one by one after clearing each or whether I should start individual new support threads for each issue after one thread is completed. I can do accordingly.

Hi ashwiniprabhu14

We have checked the search page. The issue is that you do not have the shortcode or the filters widget on that page. There is one widget area in the top section, but it is not very suitable for displaying the filters there. You need to add either a widget area in the required place with the filters widget, or use the shortcode [fe_widget] on the search page.

Best Regards,
Victor

Your message has been sent.

We have checked the site and turned off the object cache plugin, and the queries appeared in the filter set. Everything is now working as it should. The cache plugin was caching the queries on the pages and displaying only cached posts, so filtering was not affecting the cached query at all. This is why filtering was not working and why the queries were not appearing in the filter set settings.

You can turn the cache plugin back on and try to configure it so that it does not cache queries on the filter pages.

Best Regards,
Victor

Thank you.

Send you ! Your message has been sent.

We have checked the site, and what we did was duplicate a filter set and place both of them on the same page. It seems that some plugin is using page preloading to add some modifications to the page. This is where the first filter set is displayed, and after the final page is generated, filters are missing because they were created during the preloading.

Adding a second filter set fixes this issue. It does not require any extra resources or slow down the page; it simply ensures that the filters are generated in both the preloaded and the final version of the page.

Victor

I try to filter a size and the site crashes. https://sportfitonline.com/tienda/ I try to filter US size. https://sportfitonline.com/tienda/talla_us-82-11/

Help me please

Hi pantoniobmx

Everything is working fine now. Please do not create a filter from a taxonomy named “Category” in filter sets used for products, especially using a similar prefix to your talla_us filter. In general, this taxonomy is not connected to products. If you are looking for product category filters, please choose “Product Category” instead of “Category.”

Please note that the support team is currently on holiday vacation until January 8, 2026. However, we will check in periodically (every 2–3 days) to provide responses where possible.

Thank you for your understanding, and we wish you Happy Holidays!

Hi pajeromasterau

If we understand everything correctly, are you referring to creating a step-by-step filter? Something like on this demo page: https://demo.filtereverything.pro/step-by-step-filtering/

And you need information on how this can be created? Or what exactly?

Best Regards,
Victor

Hi lovesfootballuk

You can go to Filters > Settings > Experimental and turn on Improved Dropdown Styles. This will make the dropdown styles the same as on the demo site.

The remaining configurations can be made via custom CSS. You can place your custom CSS in Filters > Settings > Experimental > Custom CSS.

Victor
