Added specs and realized we can use an OOUI widget that has the clear button built in! So it should be included if it's possible to use this widget for this purpose

FYI, we're planning to reuse the matching logic from the "Add more information" fieldset.

When the search term doesn't match any parameters, we'll only see the template title, then a little empty space, then the next template title and parameters? Or should there be a "no matches found" label in this case?

When multiple templates are present, should each template include its own search field, which is always visible? Or should the search field only show on each template when a parameter belonging to it is in focus?

Correct, sounds great.

I think this sound ideal, if it's not too much extra work would add this.

For now would leave it always visible, for each template if added. Might be a bit counterintuitive, if it's not showing to figure out that I need to click a parameter in order to get the search field to appear.

Deployed to the test instance.

I skipped nice-to-haves for this iteration, but would like to come back later...

Okay, I got to this after all.

Two remaining bugs:

• Doesn't show "no parameters found"
• Search shows even when the template has no parameters.

Doesn't show "no parameters found"

If we're tight on time, this is acceptable to leave out for testing
