The Number Range Slider form element allows the user to select a range of numbers using a slider control or by typing numbers in the Start and End fields.
To use a Number Range Slider, drag the Start handle to the left or right (
). The Start field box shows the currently selected number. Then drag the End handle to the left or right (
). The End field box shows the currently selected number. Alternatively, the user can use the arrows 
to change the number (
) or type a number directly into the Start or End field boxes.

The Number Range Slider can also be manipulated using keyboard shortcuts. To use keyboard shortcuts, select the Number Range Slider form element with a left-click. Alternatively, you can use the Tab key to toggle between controls until the desired element's control has been selected. You can reverse the tabbing toggle direction by clicking Shift+TAB. Once the desired control has been selected, use the arrow keys to increase or decrease the value. This works for the manual input fields as well as the slider's endpoints.
The Start and End field's numeric value is increased with the Up arrow key and decreased with the Down arrow key.
The slider's endpoints are manipulated with the arrow keys; Down or Left to decrease the value and Up or Right to increase the value.

Number Range Slider Properties
The Properties table describes the properties of the Number Range Slider form element.
The type of a property defines what types of values the property can have. Many properties are type string, which means that the property's value is text. Boolean properties can be true or false. Some properties have more than one possible type.
Property names in Workflow Designer's Properties panel are written using the capitalization and spacing of a title. Property names in expressions are valid JavaScript identifiers and start with a lower case letter.
In the table below:
▪If a property can be accessed in both the Properties panel and expressions, then the table gives both versions of the name.
▪If a property's name in the table starts with a lower case letter, then you can only access the property in expressions.
▪If a property's name starts with a capital letter and the table does not give a name to use in expressions, then you can only access the property in the Properties panel.
Expressions are case sensitive. When you access a form element property in an expression, you must use the correct capitalization.

Number Range Slider Events
The following table describes the events associated with the Number Range Slider form element.
Events for the Number Range Slider Form Element
load |
The load event fires when the element finishes loading. You can use the load event to set one or more of the element's properties at run time. For example, you could set the element's initial value. |
change |
The change event fires when the user moves the slider's endpoints, clicks an arrow You can use the change event to create dependencies between form elements. For example, you could configure a change subworkflow that enables or disables other form elements depending on the user's selection. The change event fires every time the user's selection changes by one Step Size. This means that the change subworkflow can run multiple times. Because of this, you should make sure that the change subworkflow is not computationally intensive or long running. |
drag |
The drag event is repeatedly fired while an input is dragged. The drag event fires every time the user's selection changes by one Step Size. This means that the drag subworkflow can run multiple times. Because of this, you should make sure that the drag subworkflow is not computationally intensive or long running. |
