Lisa Brown: No, likely not. The content isn`t present in the page until someone performs an action with the search box, the crawlers won`t do that.
Morena Fiore-Kirby: Lisa Brown thank you. And having a hidden list on the page wouldn`t work either. OK thanks for confirming 👌
Zachary Toto: Morena Fiore-Kirby I`d advise against hidden content on pages. SE bots generally don`t like that. I think it`s a bad idea, not only for SEO, but general usability and experience as well as just bad development and design practice.
Morena Fiore-Kirby: Zachary Toto I`m with you, I was spelling out how that`s a bad idea anyway :)
