Movement Limits and Drag Interval

The slider limits restrict the slider thumb between a particular range. This is used if higher or lower value affects the process or product where the slider is being used.

The following are the six options in the slider’s limits object. Each API in the limits object is optional.

  • enabled: Enables the limits in the Slider.
  • minStart: Sets the minimum limit for the first handle.
  • minEnd: Sets the maximum limit for the first handle.
  • maxStart: Sets the minimum limit for the second handle.
  • maxEnd: Sets the maximum limit for the second handle.
  • startHandleFixed: Locks the first handle.
  • endHandleFixed: Locks the second handle.

Default and MinRange Slider limits

There is only one handle in the Default and MinRange Slider, so minStart, minEnd, and startHandleFixed options can be used. When the limits are enabled in the Slider, the limited area becomes darken. So you can differentiate the allowed and restricted area. Refer to the following snippet to enable the limits in the Slider.
