Showing all post category on the breadcrumb

Hi Manny @mannyo, thank you for your feedback.

Although I don’t recommend showing all categories on the breadcrumb, you can get it done by using the filter ‘breadcrumb_block_get_items’. Here is the sample code:

add_filter( 'breadcrumb_block_get_items', function($items, $breadcrumb_instance) {
	if ( is_singular('post') || is_singular('page') ) {
		// Global post.
		global $post;
		
		// Overide the all breadcrumb items.
		// Reset.
		$breadcrumb_instance->reset();
		
		// Home link.
		$breadcrumb_instance->add_crumbs_front_page();

		// Get all categories.
		$categories = get_the_category( $post );
		if ( ! empty( $categories ) ) {
			foreach( $categories as $category ) {
				$breadcrumb_instance->add_item( $category->name, get_category_link( $category->term_id ) );
			}
		}

		// Current post/page.
		$breadcrumb_instance->add_item( get_the_title( $post ), get_permalink( $post ), [ 'aria-current' => 'page' ] );

		$items = $breadcrumb_instance->get_items();
	}

	return $items;
}, 10, 2);

I’ve not had time to test the above code, but that’s the idea to solve it.

There is no functionality for sorting categories on this block, but there will be a functionality for you to choose a category/taxonomy as the primary category/taxonomy to show on the breadcrumb in the future version

Thanks, Phi.
