<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!
