Joomla range Form Field Type

The range form field type provides a horizontal slider for numeric input. While the default value can be set, there is no indication of the actual value being chosen, just the position of the slider’s thumb. It is available from Joomla 3.2 version.

Example XML field definition:

<field name=“myrange" type="range" default=“0" label="Range from -0.5 to 0.5 step 0.1" description="" min=“-0.5" max=“0.5" step="0.1" />

This will create a slider with possibility to choose values between 0 and 0.5 and change current value by 0.1 as the slider is moved left or right.
