The number of handles can be set using the start option. This option accepts an array of initial handle positions. Set one value for one handle, two values for two handles.
The number of handles in the start option is not limited to two. The connect option can be used between every handle.
All values on the slider are part of a range. The range has a minimum and maximum value. If the minimum value is equal to the maximum value, handles are evenly spread across the slider.
The amount the slider changes on movement can be set using the step option.
noUiSlider offers some powerful mechanisms that allow a slider to behave in a non-linear fashion. Sliders can be created with ever-increasing increments by specifying the value for the slider at certain intervals. Note how the handle in the example below starts at 30% of the slider width, even though 4000 is not 30% of the span between 2000 and 10000.
For every sub-range in a non-linear slider, stepping can be set. Note how in the example below the slider doesn't step until it reaches 500. From there on, it changes in increments of 500, until it reaches 4000, where increments now span 1000.
Note that the step option, when set, only applies to the first sub-range.
When a non-linear slider has been configured, the snap option can be set to true to force the slider to jump between the specified values.
Using the steps API, the sliders previous and next steps can be retrieved.
The examples section demonstrates how this API can be used.
