Similar to the buttons, input boxes can be edited on a per-UI state basis. The states available are: default, disabled, focused, hover and invalid.
Input boxes are used in any question type that involves the responder to type in information.
Menus are dropdown boxes that can be used in select questions. Menu items inherit from the input style by default, but can be overridden in the Menus menu in the style tab.
There are two key pieces to the menus: items and container. Using the items tab, you can control how the each of the options in the menu will look like. Container tab will let you customize the box that the items are enclosed in.
