You need to conform TDDropdownListDelegate to get the selected item of dropdown list.

Pass the string array to initialize() function that you want to show.

##Customization

initialize(data: [String],selectedItemColor: UIColor = UIColor(red:0.74, green:0.03, blue:0.11, alpha:1.00),itemColor:UIColor = UIColor(red:0.03, green:0.30, blue:0.53, alpha:1.00),textColor: UIColor = .white,selectedItemPlaceholder:String = "\u{02304}" , animationTimer: Double = 0.5)

In the initialize() function you can customize the UI of the library.

You can;

• Change the background color of selected item using selectedItemColor: UIColor parameter
• Change the background color of extended items using itemColor:UIColor parameter
• Change the text color using textColor: UIColor
• Change the placeholder of the selected item for the first time running using selectedItemPlaceholder:String.You can also provide Unicode characters.
• Chance the animation time of expanding using animationTimer: Double parameter
