- type (mandatory) must be radio.
- name (mandatory) is the unique name of the parameter.
- label (mandatory) (translatable) is the descriptive title of the field.
- default (optional) is the default radio button item value.
- description (optional) (translatable) is text that will be shown as a tooltip when the user moves the mouse over the drop-down box.
The XML <param> element must include one or more <option> elements which define the individual radio button items. The text between the <option> and </option> tags is shown as the label for the radio button and is a translatable string. The <option> tag takes the following argument:
- value (mandatory) is the value that will be saved for the parameter if this item is selected.
Tip: Don't forget to close the parameter definition with </param>.
Example XML parameter definition:
<param name="myradiovalue" type="radio" default="0" label="Select an option" description="">
<option value="0">1</option>
<option value="1">2</option>
</param>
