Is there a way to display Woocommerce nav filter widget filters for shop page in all headers?

I didn’t found any documentation at all on how to do this. So here comes the work arround that worked for me.

1. Register a sidebar in the functions.php file (you can change the name to whatever you want):

   function meir_widgets_init() {
       register_sidebar( array(
           'name' => 'Filters Sidebar',
           'id' => 'filters-sidebar',
           'description' => 'Sidebar for top filters.',
           'before_widget' => '<div id="%1$s" class="widget %2$s">',
           'after_widget' => '<div class="clear"></div></div></div></div>',
           'before_title' => '<h3 class="widget-title">',
           'after_title' => '</h3><div class="filter_box"><div class="filter_wrapper">',
       ) );
   add_action( 'widgets_init', 'meir_widgets_init' );
   

2. At the end of the functions.php file:

   if (!is_admin()) {
   function woocommerce_price_filter_init2() {
       global $woocommerce;
   
       //if ( is_active_widget( false, false, 'price_filter', true ) && ! is_admin() ) {
   
           $suffix = defined( 'SCRIPT_DEBUG' ) && SCRIPT_DEBUG ? '' : '.min';
   
           wp_register_script( 'wc-price-slider', plugins_url('/woocommerce/assets/js/frontend/price-slider' . $suffix . '.js', __FILE__));
           wp_enqueue_script('wc-price-slider','',true);
   //      array( 'jquery-ui-slider' ), '1.6', true );
   
       wp_enqueue_script('jquery-ui-slider', false, array('jquery'), false, true);
   
           add_filter( 'loop_shop_post_in', 'woocommerce_price_filter' );
       //}
   }
   
   add_action( 'init', 'woocommerce_price_filter_init2' );
   }
   
   
   function my_plugin_body_class($classes) {
       $classes[] = 'woocommerce';
       $classes[] = 'woocommerce-page';
       return $classes;
   }
   
   add_filter('body_class', 'my_plugin_body_class');
   

3. After that Create a folder inside your template named cache-woocommerce-nav-filter

4. In the template page you want to display the custom filters (our sidebar in this case is named filters-sidebar but can be change to anything else:

   if(!function_exists('dynamic_sidebar')){
   
           }
   
           else{
   
               $hrcachfold = plugin_dir_path( __FILE__ )."cache-woocommerce-nav-filter/";
               $hrcachefile = $hrcachfold.date("YmdH")."-cache.php";
               $shop_page_url = get_permalink( woocommerce_get_page_id( 'shop' ) );
               $actual_link = "http://".$_SERVER["HTTP_HOST"].$_SERVER["REQUEST_URI"];
   
               if ( is_shop() ) {
                   if ( ($actual_link == $shop_page_url) AND !file_exists($hrcachefile) ) {
   
                       foreach ( glob ( $hrcachfold."*-cache.php" ) as $v ) {
                           unlink ($v);
                       }
   
                       ob_start();
   
                       dynamic_sidebar('filters-sidebar');
   
                       $content = ob_get_contents();
   
                       $f = fopen( $hrcachefile, "w" );
   
                       fwrite( $f, $content );
   
                       fclose($f);ob_end_clean();
                   }
   
                   dynamic_sidebar('filters-sidebar');         
               }
   
               else {
   
                   $shoppage = file_get_contents($shop_page_url);
   
                   if ( ($actual_link == $shop_page_url) AND !file_exists($hrcachefile) ) {
   
                       foreach ( glob ( $hrcachfold."*-cache.php" ) as $v ) {
   
                           unlink ($v);
   
                       }
   
                       ob_start();
   
                       dynamic_sidebar('filters-sidebar');
   
                       $content = ob_get_contents();
   
                       $f = fopen ( $hrcachefile, "w" );
   
                       fwrite( $f, $content );
   
                       fclose ($f);
   
                       ob_end_clean();
                   }
   
                   include($hrcachefile);
               }
   
           }
