Hi Philip, first of all, thanks for your quick answer.
The situation is the next: we need to enable or disable categories by date range, such as Category: Clean Products have to be enable from 29/09 to 10/10 and thus go through various ranges of dates, because we have a trimestral order provision system to deliver products, so the user have to not see the option to select any categorie that is disable. If is this posible or any idea of a manual solution I can implement, will be welcome. Thanks again and regards!
