There is a lot of things happening in Google Knowledge Panel, Here is an example given in the above image where the search of Amish was done in mobile and in “people also search for” section & then click on more link, you will see a scrollable carousel unit with more options in people also search for section.
This was first noted by Mordy Oberstein shared the screenshots of same over Twitter:
Anyone ever see People Also Search For as in-links within a Knowledge Panel? Clicking “more” takes you to a SERP w. scrollable sets of “People Also Search For result cards”

Barry Schwartz of SERoundtable made a small GIF on same.
