Slider
Sliders are used to set linear values while providing intuitive visual feedback.
Overview
Sliders allow users to view a selected value, or range of information. Sliders provide a visual indicator, or handle of the current value, which is adjustable. This allows the user to increase or decrease the value(s) by moving the Slider's handle along a horizontal track.
Configurable properties support the ability to add ticks, labels with label, precision handles with precise, and a histogram with has.
Usage
