Filter multiple fields

Hello, is it possible to allow the user to filter by more than one category? Currently the form displays radio buttons and not checkboxes meaning the user can only select one category.
Thanks.

Hello jamesGD (I’m another Customer)

There is an addon for this from highwarden on codecanyon: https://codecanyon.net/item/multi-category-addon-for-wordpress/13486763?s_rank=5

Hope this helps
Cheers
