Zip Code Filter

[avaleske]

Add filtering by zip code (and multiple zip codes?)

This will need:

• Add support for IN comparison for lists #255
• A UI Component to add multiple things to a text field

The current mocks show a text field, so I'm going to first just use a simple comma separate list where the user would just enter everything. We can talk about adding a better component that validates and separates the values later.

Thanks for taking this!
