Hi Olga,
Thanks for your quick response, however, and this is the section I found, is it correct or not?
https://gyazo.com/2bccf6f009a28b75fc2af21960cdf326, if it is correct, why I cannot find the Drop-down type? And to be honest, I do not know what “Drop-down type” you are referring to.
Looking forward to your early reply.
