There are 2 options in the CMS for adding new items.
Option 1: Automatically send new products to the shop and add them to a category. The category it's classified under is chosen by us.
Option 2: Don't automatically approve new products. With this option, the products are not automatically assigned to a category. These products then appear under "Goed te keuren" (To be approved). To turn on this option, go to settings and click the PromoBase tab.
Here you'll find the option "Keur nieuwe producten goed bij gevonden categorie" (Approve new products for the found category). This option is enabled by default. If you want to use option 2, you can untick this checkbox.
