Google has now allowed searchers filter down their search results and/or expand their search results using a carousel-style slider at the top of either desktop or mobile search results.  With many searches, including

[baby clothes], [kids clothing], Google will show you this slider.

Check out the screenshots of both mobile and desktop:

When clicking on an item, it doesn’t seem to filter within your existing search.  Rather, it’ll take  you to a whole new search.  By searching for kids clothes, and a shoe filter shows you results for shoes, not kids’ shoes.
