Joomla number Form Field Type

The number form field type provides a HTML5 text box with arrows. If the field has a value saved, this value is displayed when the page is first loaded. If not, the default value (if any) is used. This field is available from Joomla 3.2.

Example XML field definition:

<field name="mynumbervalue" type="number" default="0" label="Choose an number" description="" min="0" max="10" step="1" />

This will create a number box with possibility to chose values between 0 and 10 and change current value by 1 each time user click up or down field button.
