LvlCodeDisplayDefinitionabstract
1groupUI controls relevant to organizing groups of questionsTrue
2  listListQuestions within the group should be listed sequentially

2  footerFooterThe group is to be continuously visible at the bottom of the questionnaire
1textUI controls relevant to rendering questionnaire text itemsTrue
2  inlineIn-lineText is displayed as a paragraph in a sequential position between sibling items (default behavior)
2  promptPromptText is displayed immediately below or within the answer-entry area of the containing question item (typically as a guide for what to enter)
2  unitUnitText is displayed adjacent (horizontally or vertically) to the answer space for the parent question, typically to indicate a unit of measure
2  lowerLower-boundText 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'
2  upperUpper-boundText 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'
2  flyoverFly-overText is temporarily visible over top of an item if the mouse is positioned over top of the text for the containing item
2  helpHelp-ButtonText 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)
1questionUI controls relevant to capturing question dataTrue
2  autocompleteAuto-completeA 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.
2  drop-downDrop downA control where an item (or multiple items) can be selected from a list that is only displayed when the user is editing the field.
2  check-boxCheck-boxA 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.
2  lookupLookupA 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.
2  radio-buttonRadio ButtonA 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.
2  sliderSliderA 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.
2  spinnerSpinnerA control where a list of numeric or other ordered values can be scrolled through via arrows.
