This Pro tutorial shows how WooCommerce products that are marked featured can be output in a Bricks query loop.
Note: The built-in Products element comes with a control for showing just the Featured products. But if you want more customizability w.r.t how the products are shown, a query loop is typically used.

On the front end after implementing the tutorial:

There are at least two ways of marking products as featured:
- by clicking on the star icon in the products list admin screen
- by clicking on “Edit” under “Catalog visibility: undefined, Featured” in the Publish meta box when editing individual products and ticking “This is a featured product”.
Step 1
Edit your template/Page with Bricks.
Add a Section and inside its Container, a Block.
Since the element on which query loop is enabled becomes the repeating item, you may want to wrap it in a Container.
Enable query loop.
Post type: Products
Posts per page: -1 (to show all the featured products)

Add a Post Title linked to the post permalink or a Basic Text element in the Block having:
{post_title:link}
Step 2
Add the following in child theme‘s functions.php or a code snippets plugin:
// Limit the products to only those that are featured.
add_filter( 'bricks/posts/query_vars', function( $query_vars, $settings, $element_id ) {
if ( $element_id === 'vbxxjs' ) {
// get the full list of product visibility term ids
$visibility_term_ids = wc_get_product_visibility_term_ids();
$tax_query['product_visibility'] = [
'taxonomy' => 'product_visibility',
'field' => 'term_taxonomy_id',
'terms' => [ $visibility_term_ids['featured'] ],
];
$query_vars['tax_query'] = $tax_query;
}
return $query_vars;
}, 10, 3 );
Replace vbxxjs with the Bricks ID of the query loop element.
Note: Products set as Hidden will not be output.
