Setup

The only thing you need to do is import JNDropDownMenu, create an instance and add it to your View and conform to its datasource and delegate.

import JNDropDownMenu
let menu = JNDropDownMenu(origin: CGPoint(x: 0, y: 64), height: 40)
        menu.datasource = self
        menu.delegate = self
        self.view.addSubview(menu)

Just implement datasource and delegate same as that of Tableview

extension ViewController: JNDropDownMenuDelegate, JNDropDownMenuDataSource {
    func numberOfColumns(in menu: JNDropDownMenu) -> NSInteger {
        return 2
    }
    
    func numberOfRows(in column: NSInteger, for forMenu: JNDropDownMenu) -> Int {
        switch column {
        case 0:
            return columnOneArray.count
        case 1:
            return columnTwoArray.count
        default:
            return 0
        }
    }
    
    func titleForRow(at indexPath: JNIndexPath, for forMenu: JNDropDownMenu) -> String {
        switch indexPath.column {
        case 0:
            return columnOneArray[indexPath.row]
        case 1:
            return columnTwoArray[indexPath.row]
            
        default:
            return ""
        }
    }
    
    func didSelectRow(at indexPath: JNIndexPath, for forMenu: JNDropDownMenu) {
        var str = ""
        switch indexPath.column {
        case 0:
            str = columnOneArray[indexPath.row]
            break
        case 1:
            str = columnTwoArray[indexPath.row]
            break
        default:
            str = ""
        }
        label.text = str + " selected"
    }
}

Menu width will default to that of screensize.

Customization: There are very minimal customization available currently. You can alter color and font before setting menu datasource as follow:

    let menu = JNDropDownMenu(origin: CGPoint(x: 0, y: 64), height: 40)
    //customize
    menu.textColor = UIColor.red
    menu.cellBgColor = UIColor.green
    menu.arrowColor = UIColor.black
    menu.cellSelectionColor = UIColor.white
    menu.textFont = UIFont.boldSystemFont(ofSize: 15.0)
    
    menu.datasource = self
    menu.delegate = self
    self.view.addSubview(menu)
