Is there a way to disable all the products that are shown in a certain category? I only want to do it for a specific category and not all.
You can go to products => Categories. Then you can click on the number in the box near the right that is for the products that are in your category. That will then pull up all of the products for that category and then you can change their status.
You could also do an export/import for that category if you have a bunch of products.
Hope that helps,
