Constructor
new OO.ui.RadioSelectWidget([config])
#
RadioSelectWidget is a select widget
that contains radio
options and is used together with OO.ui.RadioOptionWidget. The RadioSelectWidget provides
an interface for adding, removing and selecting options.
Please see the OOUI documentation on MediaWiki for more information.
If you want to use this within an HTML form, such as a OO.ui.FormLayout, use OO.ui.RadioSelectInputWidget instead.
Example
// A RadioSelectWidget with RadioOptions.
const option1 = new OO.ui.RadioOptionWidget( {
data: 'a',
label: 'Selected radio option'
} ),
option2 = new OO.ui.RadioOptionWidget( {
data: 'b',
label: 'Unselected radio option'
} );
radioSelect = new OO.ui.RadioSelectWidget( {
items: [ option1, option2 ]
} );
// Select 'option 1' using the RadioSelectWidget's selectItem() method.
radioSelect.selectItem( option1 );
$( document.body ).append( radioSelect.$element );

chooseItem(item) → {OO.ui.Widget}chainable
#
Select an item or toggle an item's selection when multiselect is enabled.

This method is not identical to #selectItem and may vary further in subclasses that take additional action when users choose an item with the keyboard or mouse.
