Dropdown search

Hi.

I’m not very experienced with coding, and was trying to make dropdown search on my website according to this video Wix Code | How to Create a Search for Your Database - YouTube
So, I just wanted to copy second part of it, but can’t recognize where to replace what (my collection name and etc.). Maybe someone can help me out, to give me instruction for only dropdown search, so I don’t get confused.

Thanks for your kind help

The article Search Using a Dropdown Element explains how to do this.

Thanks
