When using a custom field - type boolean is my cart shows the 0th item I want 0 item in your cart will not show.
Is it possible?
[attachment cleanup by admin]
In Configuration/Configuration/Shopfront select the "Do not Display Product" option in the Action when a Product is Out of Stock area
Action when a Product is Out of Stock
Products Out of Stock are orderable, no special action
X Do not Display Product
Do not Display Product, if child products also out of stock
Displays 'Notify Me' instead of 'Add To Cart' button
Products Out of Stock are orderable, and the field 'Availability' below is displayed
Good luck...
