Can you dynamically render filter options based on another filter?

I have two filters on my table.  One for District.  One for Territory.  I would like the filter options in my Territory filter to render based on which District is being selected in the other filter. 

So if…
District = West

Territory filter options shown are:
West 1
West 2
West 3


District = East

Territory Filter options are:
East 1
East 2
East 3 
*West options above become hidden

Is this possible?

It is possible.  Zach documented an approach a few years ago here:
