In this example you can see the the From left to right ( Dependent) logic for cascade filtering.

“Dependent” filtering means that you will only be able to make choices in filters in the order from left to right. By default, all the filters except for the first one will be disabled. Each next filter will become available, and show a list of options only when you make the selection in the previous filter, in the order left to right.
