Business Search Radio Button
I have a category "Schools" located in Business Listings. I would like to have a "Schools" radio button search selection up there with Business and Events at the top of the search bar. Instead of users just being able to select "Business" and "Events" as shown in the image attached; Users will now be able to select "Business", "Events", "Schools". The Schools selection can either be a duplicate of the Business selection radio search button with the name Schools (Schools can be found in Business Listing) or it can connect directly to the School category depending on what is easier.
Where do I go in order to add the search by "School" radio button selection choice and how do I go about setting that up.
Thanks in advance for the help!
