How to create such microdata in google?

Question

Search Engine Optimization

I saw a markup of a competitor in the markup of the mobile version like this:

Several pictures with goods in a row, I did not find in the documentation how to implement such a miracle. There is a markup for one product in the dock, but there is no such markup for several in a row.

Answer 1

So make one picture with several products. Surely these have it, you fill out the form under the product and decide with the manager what kind of water you want. Since there is no documentation === unrealizable.
