Dashboard: Add Filter by Taxonomy

Summary

This issue will add a new filter option to the Dashboard to filter Stories, based on hierarchical taxonomy.

References

UX: Still in progress, but this issue’s implementation can be started prior to having fleshed out comps for this. We can mimic the experience described below.

For an example of what this could look like, please see All Stories in the default WordPress view for what this means. The functionality between these two spaces should be the same: a dropdown, similar to the Author in the screenshot seen above.

Alternatives Considered

No alternatives.

Acceptance Criteria

Does this epic have any performance impact?

This should not impact performance.

Does this epic have telemetry?

We could capture usage of this dropdown via telemetry.

The title of each dropdown should correspond to the name of the type

For context, the right All Categories labels will be provided in the REST API response under labels.allitems. See how the story-editor package uses taxonomy.labels.[...] everywhere as well.

There’s no need to provide this label manually (and string concatenation like “All %s” should be avoided anyway)

Having a quick look at the functionality of this PR, it is a little confusing. Why is this dropdown a mixture of taxonomy terms from different taxonomies. If you had a term of rock, in two taxonomies, how would you know which one you are selecting here? I believe it best to have a dropdown per taxonomy, not one dropdown for everything. This mirrors how WP list page does it.

@spacedmonkey Totally understand what you mean and excellent point, and I think that’s something that wasn’t clear for us picking up on the prior work slated by the previous team. At first, we thought that we were supposed to be supporting Categories (as seen in that dropdown), and then the ask was that we include All Taxonomies. Your point is right: if you had more than one same-named custom taxonomy, it would show up similarly in the dropdown.

But as far as I’m aware, even with adding custom taxonomies within Stories and that similar page view, that there’s not a space that actually shows any dropdowns for custom taxonomies, not even within the WP list style page for stories as seen below in my screenshot.

(Note: this one Story has two custom taxonomies assigned to it and one category, but there’s no indication or view to know such within this page, and no category dropdown)

But I would have hoped this would have come up with initial conversations about designing and planning this work prior to our start implementing it. Our team is pretty fresh at this work, so it’s harder for us to know (especially since our initial thought was that we were supporting categories) what’s expected if it isn’t clearly defined and scoped. If there are gaps between what’s expected, those gaps will be larger for us as a team with fresh eyes coming into this.
