Available from V9.0.0 onwards
Infiniti versions 9.0.0 onwards include the 'Numeric' question type. This is a slider type question and its operation is as follows:
The 'Numeric' question type can be found in the toolbox at the left of the window. Selecting it adds a question with Minimum, Maximum, and Width properties. It can be used in most places a user prompt can be.
If a default value is not supplied, the minimum value is used as the starting value of the question.
The question displays as a traditional slider control with the current value shown in text underneath. If no Width is defined then the control takes the full width of the page or column.
