Here's a quick article on how to hide products from your catalog in two different ways (this does not delete them, but just "hides" the products or categories).
Individual Products:
- Go to B2B Catalog (Settings > Ecommerce > B2B Catalog)
- Find product in B2B catalog and open it
- Scroll down to "Resell Product Info"
- Uncheck "Available For Sale" box
- Save changes
Entire Categories:
- Settings > Ecommerce > Categories
- Find Correct category and open it
- Scroll down to "Category Settings"
- Uncheck "Available In Catalog" box
- Save changes
TO UNDO THIS, JUST GO BACK TO THE PRODUCT OR CATALOG AND RECHECK THE BOX!
