Hi there,
first you would need to register an nw widget area with this PHP Snippet:
function woo_custom_sidebar() {
register_sidebar(array(
'name' => 'Woo Shop Widget',
'id' => 'wooshopwidget',
'description' => 'Woo Shop Widget',
'before_widget' => '<div class="wooshopwidget">',
'after_widget' => '</div>',
'before_title' => '<h3>',
'after_title' => '</h3>',
)
);
}
add_action( 'widgets_init', 'woo_custom_sidebar' );
More info here:
https://developer.wordpress.org/reference/functions/register_sidebar/
Then you can hook the widget area into your site:
<?php if(!dynamic_sidebar('wooshopwidget')) ; ?>
I am not sure how those filter widgets will behave within that hook.
