Post Category Filter allows you to filter your post categories and custom taxonomies by adding a fast and intuitive search box on top of the term lists. As you type, the list updates instantly and shows only the categories or terms that match your query, making navigation quick even on sites with hundreds or thousands of entries.
This plugin is designed for users who work with large WordPress websites, complex content structures, or extensive taxonomy sets. Instead of scrolling endlessly through long category lists, you can simply type a few letters and immediately locate the term you need. It provides a smoother editorial workflow and helps reduce time spent searching for the right category during post creation or editing.
Post Category Filter works seamlessly inside the WordPress admin interface and supports all public taxonomies, including custom taxonomies created by themes or plugins. It does not modify your categories or database in any way. It simply adds an efficient, lightweight search layer to help you manage and assign terms more effectively.
If you maintain a high volume of content, run news or magazine style websites, or organize your posts through detailed taxonomies, this plugin can significantly improve your daily publishing workflow. It is a simple but powerful solution for anyone looking to optimize category management, streamline content editing, and enhance usability in the WordPress admin area.

<h3>Taxonomy Chain Menu Features (shortcode attributes):</h3>
✅ post_slug: post type to use in the chain menu. Default slug is ‘post’.
✅ taxonomy: taxonomy terms to navigate. Default taxonomy is ‘category’.
✅ parent_id: started term ID, 0 means top parents. Default slug is 0.
✅ exclude: terms ids to hide from the chain. For example: 12,44,73.
✅ include: terms ids to show. Opposite to ‘exclude’. For example: 11,43,72.
✅ include_top: terms ids related to the top parent terms only (parent == 0). For example: 10,42,71.
✅ show_count: show/hide count of posts in the terms in drop-downs options. Default value is 0.
✅ watch_view: values: ‘posts’, ‘terms’, ‘none’. What to show on the end of the chain. Posts – drop-down with posts. Terms – button with the link to posts of the selected term in the last drop-down. None – nothing, good to apply with products tables filtering.
✅ label_taxonomy: label(s) of the drop-down(s). Example: ‘Producer’. Also it is possible to use custom actions (must started from ‘call_filter_’) for translations, example: [taxonomy_chain_menu label_taxonomy=’call_filter_chain1′ label_post=’call_filter_chain1-post’]. In file functions.php add next code:
<pre><code>add_filter('chain1', function($args) {

 $res = 'Producer';
 //for WPML compatibility as an example
 if (defined('ICL_LANGUAGE_CODE')) {
 switch (ICL_LANGUAGE_CODE) {
 case 'es':
 $res = 'Productor';
 break;
 case 'uk':
 $res = 'Виробник';
 break;
 }
 }

 return $res;
}, 10, 1);
</code></pre>
✅ label_post: label of the posts drop-down. To use action instead of text in file functions.php add next code: (must started from ‘call_filter_’)
<pre><code>add_filter('chain1-post', function($args) {

 $res = 'Select car';
 //for WPML compatibility as an example
 if (defined('ICL_LANGUAGE_CODE')) {
 switch (ICL_LANGUAGE_CODE) {
 case 'es':
 $res = 'Seleccionar coche';
 break;
 case 'uk':
 $res = 'Яке твое авто';
 break;
 default:
 $res = 'Select your car';
 break;
 }
 }

 return $res;
}, 10, 1);
</code></pre>
✅ button_title: title of the button at the end of the chain. By default it is ‘GO!’. Also is possible to use action (must started from ‘call_filter_’), example: [taxonomy_chain_menu post_slug=’product’ taxonomy=’product_cat’ button_title=’call_filter_chain1-btn’]
<pre><code>add_filter('chain1-btn', function($args) {

 $res = 'Take it!';
 //for WPML compatibility as an example
 if (defined('ICL_LANGUAGE_CODE')) {
 switch (ICL_LANGUAGE_CODE) {
 case 'es':
 $res = 'Tomar lo!';
 break;
 case 'uk':
 $res = 'Забираймо!';
 break;
 }
 }

 return $res;
}, 10, 1);
</code></pre>
✅ chain_id: (for developers)unique JavaScript identifier for javascript event ‘taxonomy-chain-menu’ and in custom WordPress actions
✅ connect_table: unique identifier of posts/products table (TABLEON or WOOT) set in table shortcode attribute or its backend settings. It is possible to use Taxonomy Chain Menu as filter with posts and products table plugins: <a href="https://posts-table.com/" rel="nofollow ugc">TABLEON – WordPress Posts Table Filterable</a> and <a href="https://products-tables.com/" rel="nofollow ugc">WOOT – WooCommerce Products Table</a> 
Such scripts cooperation is possible thanks to JavaScript event ‘taxonomy-chain-menu’ and shortcode attributes ‘chain_id’ with attribute ‘connect_table’
✅ do_filter: accepts from the box only one value – ‘woof’ (<a href="https://demo.products-filter.com/taxonomy-chain-menu" rel="nofollow ugc">demo</a>), but it is possible to adapt any another wordpress/woocommerce filter plugin (for developers) using js event taxonomy-chain-menu-do-filter and values there: e.detail.term_id, e.detail.slug, e.detail.container. Example: [taxonomy_chain_menu post_slug=’product’ taxonomy=’product_cat’ do_filter=’woof’]
✅ select_width: widths for drop-downs in chain. Use one value or some separated by ‘|’. Examples: ‘300px’, ‘300px|250px|20%’. Last value is actual for drop-downs in chain with number 3 and more.
✅ max_posts_count: set maximum count of posts in posts drop-down
✅ posts_orderby: how to order posts in posts drop-down (by title, id, meta). By default: title.
✅ posts_order: posts order direction in posts drop-down. Possible values: ASC, DESC
✅ posts_order_meta_key: here is meta key by which posts in posts drop-down should be ordered. Be care – meta values should exist in the requested posts. Example: [taxonomy_chain_menu post_slug=’product’ taxonomy=’product_cat’ posts_orderby=’meta_value_num’ posts_order_meta_key=’prod_1′ posts_order=’DESC’]
✅ no jQuery – pure JavaScript!
✅ Shortcode example [taxonomy_chain_menu post_slug=’product’ taxonomy=’product_cat’ show_count=1 exclude=’1′ include_top2=’17’ parent_id2=17 target=’_blank’ watch_view2=’terms’ label_taxonomy=’call_filter_chain1′ label_post=’call_filter_chain1-post’ chain_id=’chain1′ connect_table=’asdfgh’ ready_chain=’17,18,0′ button_title=’call_filter_chain1-btn’ do_filter2=’woof’ label_before2=’call_filter_chain1-before’ select_wrapper=’selectron23′ max_posts_count2=2 posts_orderby2=’meta_value_num’ posts_order_meta_key2=’prod_1′ selectron23_max_open_height=’150|200|220′ select_width=’300px|200px|350px’]
✅ All features above
✅ target: how to open selected post/terms page. Default is: ‘_self’ (opening in the same browser tab). To open in another tab use: ‘_blank’
✅ syntax for label_taxonomy: as an example – ‘Producer|Model’, such syntax allows to set individual title for each drop-down in the chain
✅ label_before: any words before first drop-down. Also it is possible to set text through action (must started from ‘call_filter_’): ([taxonomy_chain_menu post_slug=’product’ taxonomy=’product_cat’ label_before=’call_filter_chain1-before’])
✅ ready_chain: allows to display pre-selected values in the chain menu, example – [taxonomy_chain_menu watch_view=’posts’ ready_chain=’17,20,post(51)’] – at the end of the chain will be displayed drop-down with posts and button with the link to the selected post. If exists more sub-categories use 0 (zero) at the end: [taxonomy_chain_menu ready_chain=’17,20,0′]. <a href="https://woocommerce.wp-filter.com/simple-taxonomy-chain-menu-2/" rel="nofollow ugc">See example</a>.
✅ select_wrapper: has only one value ‘selectron23’ and allows to wrap drop-down in reach html-element Selectron23. Just <a href="https://demo.products-filter.com/taxonomy-chain-menu/?swoof=1&ready_chain=9,66,0&product_cat=wooman" rel="nofollow ugc">look an example</a> please to understand!
