Slider
Documentation
The Slider is a widget that allows a user to set a numeric value on a continuous range of possible values. Range boundaries of the Slider are specified by the min and max options. This demo illustrates how to customize the widget appearance and how to handle the value change event.
Feel free to share demo-related thoughts here.
