Dash - Clicking on a search filter category title hides the filter options

[John Lea]

Clicking on a search filter category title hides the filter options

To Reproduce:
1. Navigate to a Dash Lens, open the 'Filter results', and click on a filter category title (e.g. "Type" in the App Lens)

What currently incorrectly happens:
- All the options disappear! Repeated clicking causes the filter category below the category title clicked on to be disappear or be displayed underneath the first category. See attached images:

where_has_the_second_filter_category_gone.png
second_filter_category_is_now_underneath_the_first.png

Correct desired behaviour:

- Until the expand/collapse behaviour is working correctly, and the white rotating triangle is present, clicking on the 'search filter category title' should do nothing

- Implement the correct expand/collapse behaviour, and add the white rotating 'expanded/collapsed' triangle shown in the designs

Its a regression it was working just fine a few weeks ago.
