Filters, which depend on output of other filters
Is it possible to have filters that depend on outputs of other filters?
Rough data model:
* Each account can have many tags
* Each account can tag their tracked entities (with one or more tags)
Filter 1 -- allower users to choose the list of accounts
Filter 2 -- allow users to select the list of tags (for the selected accounts in Filter 1)
Filter 3 -- allower users to choose from the unique list of tracked entities (tagged with the selected tags)
Not quite parent-child filters. Ideas?
