|
*
|

* - tag: string|false, the tag name of the container element. False to render radio button without container.

|

|
|
* You may set this option to be null to prevent default value submission.

|
* If this option is not set, an empty string will be submitted.
|
|
* - encode: boolean, whether to HTML-encode the checkbox labels. Defaults to true.
|
|
* This option is ignored if `item` option is set.
|
|
* - separator: string, the HTML code that separates items.
|
|
* - itemOptions: array, the options for generating the radio button tag using [[radio()]].
|
|
* - item: callable, a callback that can be used to customize the generation of the HTML code
|

|
|
* ```php

|
|
* is the label for the radio button; and $name, $value and $checked represent the name,
|
|
* value and the checked status of the radio button input.
|
