1. Introduction 

The purpose of this knowledge base article is to describe the use of the Invert option in the animal filter screen. This is a new addition to Stockbook 2019. 

2. What does "Invert" do?

You will see the Invert checkboxes throughout the animal filter screen. Ticking them inverts the current filter that relates to the section the invert covers. 

If you look at the example below, if the Invert WASN'T ticked in the Sex section, it would only show male animals. However with the Invert ticked (as shown), it shows all animals EXCEPT males.
