Hide certain categories

Currently that’s not possible.

The dropdown is created with Select2 box so even if you have a long list of categories, you can search for specific category easily if you start typing into that dropdown

Thanks Lowsar.

This is now fixed with a local modification. In case anyone else needs to do this:

Modify file: plugins/woocommerce-filter-orders-by-product/inc/filter-by-category.php

Change your category IDs as needed.

public function dropdown_fields(){
	
$terms = get_terms( array('taxonomy' => 'product_cat', 'fields' => 'id=>name' ) );
$fields = array();
$fields[0] = esc_html__( 'All Orders', 'woocommerce-filter-orders-by-product' );
$fields[59] = 'Restaurant 1';
$fields[60] = 'Restaurant 2';
//		foreach ( $terms as $id => $name ) {
//			$fields[$id] = $name;
//		}
return $fields;
}
