Add selected categories.

Hi, I hope you doing well. We are using your plugin for our WordPress website. So we have several categories for products and we want the search field to have custom categories or selected categories instead display all. For example, These are categories:

Hp, Dell, Lenovo, Samsung

We want to create a search field with the label: Brand and want to have all these above categories under that.

And so on to the next search field for example these are categories:

2001, 2002, 2003, 2004, 2005 and 2006

We want to create a search field with the label: Years and we want to have all these categories only.

So in that way, we want to create multiple fields with selected categories only but we are unable to fund any solution within the plugin. Looking forward to your positive response.
Thank you!
