I asked my developer if your reply resolved his issues. He said this:

“Nope, this is a different thing, it’s used as a custom horizontal form in the hero section, just like we normally see on Travel websites.

This also doesn’t have Tags option, it works with attributes.

Making the question more specific for them:
We need to have the WooCommerce Widget Filters load with Ajax, it does filter the Category, Price, and Attributes with Ajax, but the Tags don’t use Ajax and it reloads the page. Please see attached screenshot.”
