Description of problem:

The checkbox to toggle between applicable errata and installabe errata in the errata content hosts page is missing because of the following typo in the html template.

engines/bastion_katello/app/assets/javascripts/bastion_katello/errata/details/views/erratum-content-hosts.html

&lt;div class="filters"&gt;    <=========== Class should be replaced with "data-block" 
    &lt;label class="checkbox-inline"&gt;
      &lt;input type="checkbox" ng-model="restrictInstallable" ng-change="toggleInstallable()"/&gt;
      &lt;span translate&gt;Only show content hosts where the errata is currently installable in the host's Lifecycle Environment.&lt;/span&gt;
    &lt;/label&gt;
  &lt;/div&gt;
