Have a documents content type, with three taxonomies applied to it. Taxonomies are document type (form, policy, other), document group (hr, i.t., training, project specific, etc.), and a free-tagged project name (for when document group = project specific).
Have single view displaying all documents, segregated by tabbed page displays:
- All page/tab is for all docs
- Forms page/tab is limited to doc type = form
- Policy page/tab is limited to doc type = policy
- Project Specific Docs is limited to doc group = project specific
Exposed Filter on individual pages:
- Within Form and Policy pages, we offer an exposed filter of document groups as dropdown control. So for instance on the forms page you can quickly filter to just HR forms.
- On the project specific docs page, we offer an exposed filter of project names, so you can quickly filter to your project, but these docs can be forms and/or policy.
Now that we have the project specific page/tab, we want to remove 'project specific docs' taxonomy term from the Forms and Policy page/tabs dropdown filter on just those two views page displays. It's already filtered out, so if you select Project Specific Docs on those pages you get no results. Just need to remove the option from the select list.
UPDATE: found my own answer
