/**
* Renders a list of radio buttons.
* A radio button list is like a checkbox list, except that it only allows single selection.
* The selection of the radio buttons is taken from the value of the model attribute.
* @param array $items the data item used to generate the radio buttons.
* The array values are the labels, while the array keys are the corresponding radio values.
* Note that the labels will NOT be HTML-encoded, while the values will.
* @param array $options options (name => config) for the radio button list. The following options are specially handled:
*
* - unselect: string, the value that should be submitted when none of the radio buttons is selected.
* By setting this option, a hidden input will be generated.
* - separator: string, the HTML code that separates items.
* - item: callable, a callback that can be used to customize the generation of the HTML code
* corresponding to a single item in $items. The signature of this callback must be:
*
* ~~~
* function ($index, $label, $name, $checked, $value)
* ~~~
*
* where $index is the zero-based index of the radio button in the whole list; $label
* 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.
* @return static the field object itself
