Hello, i was wondering how to do i implement custom field with listings that are sorted thru category, i want to whenever user chooses category of cities “new york boston la” etc to display another value at header of that page, problem is that there is no post or page related to that so i dont know how to link it exactly, web url goes something like this if it helps “www.example.com/listings/?search_keywords=” and accessing the search of those categories is going thru homepage and clicking on search field
