How to create a Custom filter tree

After the installation, the  Default filter displays on all Collection pages. Based on your needs, you can create a Custom filter tree with a specific set of filter options for a specific collection. The Custom filter tree will not inherit from the Default filter.
Note: If a collection is already associated with an existing custom filter tree, you will not be able to associate it with another one. At the moment, we do not support showing multiple filter trees on a collection.
