I need help. I need to add a calendar to a product page in Shopify so that a customer can select a date. The minimum shipment date of the goods is recorded in the metafield. I need the date in the calendar for the client to start from the date specified in the metafield. The calendar should be displayed on pages for which there is a date in metafields. There are also pages for which there is no date and “0” is written in the metafields, and for these products you do not need to add a calendar to the page. Can you help me with this?
