Radio buttons

Radio field renders a set of radio buttons. Supports initial checked or disabled attributes.

Example configuration

...
array(
    'title' => 'My radio field title',
    'id' => 'radio-option',
    'desc' => 'Short description for the field',
    'tab' => 'main',
    'type' => 'radio',
    'choices' => ['First label', 'Second label', 'Third label']
),
...

This will produce the following

It will use the label text as the value. If you wish to separate values from labels use the following syntax for the choices key:

...
'choices' => array(
    array(
        'value' => 'First value',
        'label' => 'First label',
    ),
    array(
        'value' => 'Second value',
        'label' => 'Second label',
    ),
    array(
        'value' => 'Third value',
        'label' => 'Third label',
    ),
)
...

checked and disabled

If checked or disabled keys are specified, they'll be respected. E.g:

...
'choices' => array(
    array(
        'value' => 'First value',
        'label' => 'First label',
    ),
    array(
        'value' => 'Second value',
        'label' => 'Second label',
        'checked' => true,
    ),
    array(
        'value' => 'Third value',
        'label' => 'Third label',
        'disabled' => true,
    ),
)
...

will result in the following

Notice that the second option is checked on initial page load and the third option is not checkable.
