Discrete Sliders look and feel similar to continuous sliders but the cursor can only be dragged to specified points along the slider, so essentially it is a horizontally orientated Single Selection question. You can set as many values as you like, but the user is forced to choose only one of them.
Changing the number in the "# Answers" box will automatically add or subtract answer lines for you to edit.
On the app screen each possible response illuminates as the cursor get closer to it. When released, the cursor snaps to the closest defined value.
