I am building a Second Hand Cars and Bikes selling website and I am using MIGX with custom Database Tables for fields like car/bike color, year of purchase, model etc. Everything is smooth and easy to display on front end. But client want visitors to search and filter fields. Like on Cars page, there is a search and filter area where there is drop down/multi select boxes from which visitors can select and filter cars based on fields like colors, models etc. can anyone suggest me how to make this search and filter capability with Migx ?
