Description of problem:
In the Packages/Errata view, there is an associated picker which, when clicked, exposes a filter bar. However, this filter bar is not for the content within the view, it is for the contents within the picker itself.

When the picker only had two options, this is unnecessary, and in fact confusing in the UI.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  sync a rhel repo
2.  Content Search, in the left pane, choose a content type of "repos"
3.  In the first repos field, search for Red*
4. In the search results, hover over one of the content markers and choose either "Packages" or "Errata"
5. On the ensuing results view, atop the results, there is a "Show ________v" dropdown. Click it.
6. In the resulting search box, enter text, thinking this is a search filter for the results below.
  
Actual results:
No matches because this _isn't_ a filter for the results below. It is a filter for the contents of the dropdown box itself (i.e., try typing 'Erra' in this box)

Expected results:
We don't need this search box when there are only two options in this dropdown. It also is misleading, as users might think they're filtering on the search results, and this isn't the case.


Additional info:

[11:28] <cswiii> that seems like a bit of overkill
[11:28] <cswiii> when there are two dropdown options
[11:31] <ehelms> I would agree, built-in to the plugin, which we can fork and update
