This article explain B2BKing Advanced Visibility Settings
Dynamic rules for all users in hybrid mode
The purpose of the hybrid mode in B2BKing is to allow buyers to install B2BKing on existing stores and not have to worry about configuration and changes that could confuse existing users. It aims to maintain an identical experience for B2C users.
However in certain cases you may still want to apply dynamic rules to b2c and guest users. In this case, you should enable Dynamic rules for all users in hybrid mode
Hidden has priority
What happens if a product is part of multiple categories, some visible and some not? The default B2BKing behaviour is: if a product is part of at least 1 visible category, the product will be visibile
The setting "Hidden has priority" reverses this, so that: if a product is part of at least 1 hidden category, the product will be hidden
