Wijmo UI for the Web
range Option
wijmo.slider.wijslider Namespace > options type : range Option

Default value: false

The range option, if set to true, allows the slider to detect if you have two handles.

Syntax
$(function () {
    
    // Get value
    var returnsValue; // Type:  boolean
    returnsValue = $(".selector").wijslider("option", "range");
    
    // Set value
    var newValue; // Type:  boolean
    $(".selector").wijslider("option", "range", newValue);
        
});
var range : boolean;
Remarks
It will then create a stylable range element between the two handles. You can also create a stylable range with one handle by using the 'min' and 'max' values. A min range goes from the slider min value to the range handle. A max range goes from the range handle to the slider max value.
