  Code	Display	Definition
  autocomplete	Auto-complete	A control which provides a list of potential matches based on text entered into a control. Used for large choice sets where text-matching is an appropriate discovery mechanism.
  check-box	Check-box	A control where choices are listed with a box beside them. The box can be toggled to select or de-select a given choice. Multiple selections may be possible.
  drop-down	Drop down	A control where an item (or multiple items) can be selected from a list that is only displayed when the user is editing the field.
  flyover	Fly-over	Text is temporarily visible over top of an item if the mouse is positioned over top of the text for the containing item
  footer	Footer	The group is to be continuously visible at the bottom of the questionnaire
  group		UI controls relevant to organizing groups of questions
  header	Header	The group is to be continuously visible at the top of the questionnaire
  help	Help-Button	Text is displayed in a dialog box or similar control if invoked by pushing a button or some other UI-appropriate action to request 'help' for a question, group or the questionnaire as a whole (depending what the text is nested within)
  inline	In-line	Text is displayed as a paragraph in a sequential position between sibling items (default behavior)
  list	List	Questions within the group should be listed sequentially
  lookup	Lookup	A control where editing an item spawns a separate dialog box or screen permitting a user to navigate, filter or otherwise discover an appropriate match. Useful for large choice sets where text matching is not an appropriate discovery mechanism. Such screens must generally be tuned for the specific choice list structure.
  lower	Lower-bound	Text is displayed to the left of the set of answer choices or a scaling control for the parent question item to indicate the meaning of the 'lower' bound. E.g. 'Strongly disagree'
  prompt	Prompt	Text is displayed immediately below or within the answer-entry area of the containing question item (typically as a guide for what to enter)
  question		UI controls relevant to capturing question data
  radio-button	Radio Button	A control where choices are listed with a button beside them. The button can be toggled to select or de-select a given choice. Selecting one item deselects all others.
  slider	Slider	A control where an axis is displayed between the high and low values and the control can be visually manipulated to select a value anywhere on the axis.
  spinner	Spinner	A control where a list of numeric or other ordered values can be scrolled through via arrows.
  table	Table	Questions within the group are rows in the table with possible answers as columns
  text		UI controls relevant to rendering questionnaire text items
  text-box	Text Box	A control where a user can type in their answer freely.
  unit	Unit	Text is displayed adjacent (horizontally or vertically) to the answer space for the parent question, typically to indicate a unit of measure
  upper	Upper-bound	Text is displayed to the right of the set of answer choices or a scaling control for the parent question item to indicate the meaning of the 'upper' bound. E.g. 'Strongly agree'
