Improvement of the Content Creation Widget "Filtering by group" feature, moving from the checkboxes options to a dropdown list.

*BDD:
When I click on "Filter by" button,
then I can see a dropdown list (default item selected - Content).
When I click on a different list item,
then I can see how the dropdown list closes and the available content types list is refreshed.
When I click on any given content type,
then I am taken to the view where I can edit it.

Images attached showing the behavior as well as in the different cases where the CCW is used.
