Hi. Could someone tell me how to create a search engine for wix? Basically, I want four buttons which say, for instance, a, b,c and d. When one hovers your cursor over each button you will see the same 4 options, for instance, I., II., III., IV. When you click one of these options, say option I, it takes you to a search engine in which you will be able to search for all the parts under option I and will also list down the parts under option I. The parts for option I under a will not necessarily be the same as the parts under options I for b,c and d. I hope this makes sense.
