Google on mobile search has a new box for “browse more ideas” for some queries. This box shows is a fancy query refinement to get you to do more searches to refine your query to something more specific.
For example, a search for [beach ideas] will show query refinement options for [beach date ideas], [ideas for beach trips], [beach gift ideas] and [beach party ideas]. Here is a screenshot:

Clicking on any of these conducts another search in Google for that query.
This was first spotted by Saad AK who posted more examples on Twitter:
Hi @rustybrick SIR,
I am seeing “Browse more ideas” feature in the Google SERPs. It might be new.
Some queries (out of many) which triggered it:
1: painting kitchen cabinet ideas
2: beach ideas
3: indoor birthday party ideas
4: new ideas for home decorCC: @Suzzicks MAM. pic.twitter.com/EvPNPU4qF2

Brodie Clark convinced me it was new:
Pretty sure this one is new btw. That post you linked is related to eComm for the Popular Products carousel. This one is more focused on blogs/guides. Clicking one of the options just takes you to another search though (pretty basic function). pic.twitter.com/sQ2gGMohrY
