+Radios are objects, where the user can choose between different items.<br>
+Here is a example of how to create a standard radio:
+
+````lua
+local mainFrame = CreateFrame("myFirstFrame"):show()
+local aRadio = mainFrame:addRadio("myFirstRadio"):show()
+````
+
+This will create a default radio on position 1 1 (relative to its parent frame), the default background is colors.lightBlue, the default text color is colors.black and the default zIndex is 5.
+
+Here are all possible functions available for radios. Remember radio inherit from [object](https://github.com/NoryiE/NyoUI/wiki/Object):
+

+````lua
+local mainFrame = NyoUI.createFrame("myFirstFrame"):show()

+aRadio:addItem("1. Entry")
+aRadio:addItem("2. Entry",5,1,colors.yellow)
+aRadio:addItem("3. Entry",5,4,colors.yellow,colors.green)
+````
+**args:** text, x, y bgcolor, fgcolor, ..., text is the displayed text, x and y are the position, where you want the item to be created, bgcolor and fgcolors the colors of background/text and args (...) is something dynamic, you wont see them but if you require some more information per item you can use that.<br>
