It expands and collapses. It allows the user to select only one item at a time. Items are just Strings. A delegate is notified when selection occurs. DKDropMenu is IBDesignable and IBInspectable with customizable colors, font, and row heights. 3 | 4 | ![DKDropMenu1](https://raw.githubusercontent.com/davecom/DKDropMenu/master/DKDropMenu.png) 5 | ![DKDropMenu2](https://raw.githubusercontent.com/davecom/DKDropMenu/master/DKDropMenu.gif) 6 | 7 | ## Installation 8 | Use the cocoapod `DKDropMenu` or simply include `DKDropMenu.swift` in your project. DKDropMenu 0.3.0 and above requires Swift 4. Use version 0.2.0 for Swift 3 Support. Use version 0.1.6 for Swift 2 support. 9 | 10 | ## Usage 11 | Create a DKDropMenu in IB or in code (using UIView's init methods). Then add items and set a delegate: 12 | ``` 13 | dropMenu.add(names: ["hello", "goodbye", "why?"]) 14 | dropMenu.delegate = self 15 | ``` 16 | Make sure to implement the single method the delegate (DKDropMenuDelegate) must implement: 17 | ``` 18 | func itemSelected(withIndex: Int, name: String) { 19 | println("\(name) selected"); 20 | } 21 | ``` 22 | The delegate can also optionally implement the method 23 | ``` 24 | func collapsedChanged() 25 | ``` 26 | to be notified when the collapse status of the menu changes. 27 | 28 | Items can be added or removed 29 | ``` 30 | func add(names: [String]) 31 | func add(name: String) 32 | func remove(atIndex: Int) 33 | func remove(name: String) 34 | func removeAll() 35 | ``` 36 | The properties `collapsed` (Bool) and `selectedItem` (String) can be manually modified. 37 | 38 | ## License and Authorship 39 | Released under the MIT License.
