Breadcrumb Block

This is a single-block plugin for the breadcrumb trail. It’s simple, lightweight, SEO-friendly, and WooCommerce compatibility. It also includes some simple separator icons.

How to customize the breadcrumb

1. How to change the markup of the block?

   add_filter( 'breadcrumb_block_get_breadcrumb_trail', function ( $markup, $args, $breadcrumbs_instance ) { return $markup; }, 10, 3 ); 

2. How to add or remove the items from the breadcrumb trail?

   add_filter( 'breadcrumb_block_get_items', function ( $items, $breadcrumbs_instance ) { return $items; }, 10, 2 ); 

3. How to use a custom separator for the breadcrumb trail?

   add_filter( 'breadcrumb_block_get_args', function ( $args ) { // For example, change separator. $args['separator'] = '<svg xmlns="http://www.w3.org/2000/svg" fill="currentColor" width="1em" height="1em" viewBox="0 0 16 16"><path fill-rule="evenodd" d="M3.646 1.646a.5.5 0 0 1 .708 0l6 6a.5.5 0 0 1 0 .708l-6 6a.5.5 0 0 1-.708-.708L9.293 8 3.646 2.354a.5.5 0 0 1 0-.708z"/><path fill-rule="evenodd" d="M7.646 1.646a.5.5 0 0 1 .708 0l6 6a.5.5 0 0 1 0 .708l-6 6a.5.5 0 0 1-.708-.708L13.293 8 7.646 2.354a.5.5 0 0 1 0-.708z"/></svg>'; return $args; } ); 

   The custom separator should be an inline SVG. To make sure it displays properly, it should have three attributes: width, height, and fill. The values of these attributes should be as follows: fill="currentColor" width="1em" height="1em".
   Using this hook, you can customize other attributes such as container, before, after, list_tag, item_tag, item_before, item_after, separator.
